Windows Server is the platform for building an infrastructure of connected applications, networks, and web services, from the workgroup to the data center. It bridges on-premises environments with Azure, adding additional layers of security while helping you modernize your applications and infrastructure.

Get started with Windows Server: R2. Windows Server Essentials edition is a cloud-connected first server designed for small businesses with up to 25 users and 50 devices. If you are considering installing any version of Windows Server Essentials, we would encourage you to consider Microsoft Get started with Windows Server Essentials: R2. Automatic tiering can be lots of helpful, as it can create tons of space in your storage. Not only it is limited to create space but it can also transfer huge number of data between a various range of storage that are present in the servers.

Deduplication can remove all those duplicated or identical files in your Virtual Hard drive. Which later on the record of those useless file are saved in System Volume Information SVI and while in case of need, system points to the files the server have as a resource. In short, it can help you to save a tremendous amount of space.

UEFI based virtual machines are introduced. DSC feature is now inducted in Windows Power Shell, whereas Windows Defender is on duty to protect your computer from malware and also to prevent cyber-attacks.

GUI-less install option is available. This feature provides you ways to install Windows Server on your computer.

You can now install Windows Server on your computer without installing any other application attached. No installation of unnecessary apps can reduce disk space and saves administrators efforts. Storage pinning is also introduced which was handy. As, it wont let the small or big file to stack themselves. Putting pins on your files can make them organized and ensures to have a better storage management. Write Back Cache is a feature which helps to keep a record of input and output characteristic of your machines.

The feature can be used for finding the reason behind its last lag or crash. As you have burned the ISO file on your drive, restarts your computer.

The following examples illustrate how to apply affinity rules for various scenarios, using the different features of the affinity group capability described in this chapter.

Dalia is the DevOps engineer for a startup. Adds the two virtual machines, VM01 and VM02 , to the affinity group. Sets VM Affinity to Negative so the virtual machines try to run on separate hosts. Leaves Enforcing cleared disabled so that both virtual machines can continue running in case only one host is available during an outage.

Leaves the Hosts list empty so the virtual machines run on any host in the cluster. Sohni is a software developer who uses two virtual machines to build and test his software many times each day. There is heavy network traffic between these two virtual machines. Running the machines on the same host reduces both network traffic and the effects of network latency on the build and test process. Adds VM01 and VM02 , the build and test virtual machines, to the affinity group.

Adds the high-specification hosts, host03 , host04 , and host05 , to the affinity group. Sets VM affinity to Positive so the virtual machines try to run on the same host, reducing network traffic and latency effects.

Sets Host affinity to Positive so the virtual machines try to run on the high specification hosts, accelerating the process. Leaves Enforcing cleared disabled for both rules so the virtual machines can run if the high-specification hosts are not available.

Bandile, a software asset manager, helps his organization comply with the restrictive licensing requirements of a 3D imaging software vendor. Additionally, the physical CPU-based licensing model requires that the workstations run on either of two GPU-equipped hosts, host-gpu-primary or host-gpu-backup. To meet these requirements, Bandile creates an affinity group called “3D seismic imaging” and does the following:. Sets VM affinity to Positive and selects Enforcing so the licensing server and workstations must run together on one of the hosts, not on multiple hosts.

Sets Host affinity to Positive and selects Enforcing so the virtual machines must run on either of the GPU-equipped the hosts, not other hosts in the cluster. Understand that an affinity label is the equivalent of an affinity group with a Host affinity rule that is Positive and has Enforcing enabled.

Understand that if an affinity label and affinity group conflict with each other, the intersecting set of virtual machines do not run.

Otherwise, a conflict is not possible. Inspect the affinity groups. They must contain a rule that has Enforcing enabled. Inspect the affinity labels and groups. Make a list of virtual machines that are members of both an affinity label and an affinity group with an Enforcing option enabled. For each host and virtual machine in this intersecting set, analyze the conditions under which a potential conflict occurs. If you have overlapping affinity groups and affinity labels, it can be easier to view them in one place as affinity groups.

Consider converting an affinity label into an equivalent affinity group, which has a Host affinity rule with Positive selected and Enforcing enabled. Affinity labels are used to set hard Enforced positive affinity between virtual machines and hosts. See the Affinity Groups section for more information about affinity hardness and polarity.

Labels function identically to a hard positive affinity group, but simplify configuration in certain use cases. For example, if you have virtual machines that require specific host hardware, you can use affinity labels to ensure that those virtual machines run on the required hosts. If you use software that is license-limited to a certain number of physical machines, you can use affinity labels to ensure that virtual machines running that software are limited to the required physical hosts.

Affinity labels are a subset of affinity groups and can conflict with them. If there is a conflict, the virtual machine will not start. You can create affinity labels from the details view of a virtual machine, host, or cluster.

This procedure uses the cluster details view. Click Compute Clusters and select the appropriate cluster. Use the drop-down lists to select the virtual machines and hosts to be associated with the label.

You can edit affinity labels from the details view of a virtual machine, host, or cluster. The export storage domain is deprecated. Storage data domains can be unattached from a data center and imported to another data center in the same environment, or in a different environment. Virtual machines, floating virtual disks, and templates can then be uploaded from the imported storage domain to the attached data center.

You can export virtual machines and templates from, and import them to, data centers in the same or different Red Hat Virtualization environment.

You can export or import virtual machines by using an export domain, a data domain, or by using a Red Hat Virtualization host. When you export or import a virtual machine or template, properties including basic details such as the name and description, resource allocation, and high availability settings of that virtual machine or template are preserved.

The permissions and user roles of virtual machines and templates are included in the OVF files, so that when a storage domain is detached from one data center and attached to another, the virtual machines and templates can be imported with their original permissions and user roles. In order for permissions to be registered successfully, the users and roles related to the permissions of the virtual machines or templates must exist in the data center before the registration process.

V2V converts virtual machines so that they can be hosted by oVirt. Export a virtual machine to the export domain so that it can be imported into a different data center. Before you begin, the export domain must be attached to the data center that contains the virtual machine to be exported. Optionally, select the following check boxes in the Export Virtual Machine window:. Force Override : overrides existing images of the virtual machine on the export domain.

Collapse Snapshots : creates a single export volume per disk. This option removes snapshot restore points and includes the template in a template-based virtual machine, and removes any dependencies a virtual machine has on a template. For a virtual machine that is dependent on a template, either select this option, export the template with the virtual machine, or make sure the template exists in the destination data center. When you create a virtual machine from a template by clicking Compute Templates and clicking New VM , you wll see two storage allocation options in the Storage Allocation section in the Resource Allocation tab:.

If Clone is selected, the virtual machine is not dependent on the template. The template does not have to exist in the destination data center. If Thin is selected, the virtual machine is dependent on the template, so the template must exist in the destination data center or be exported with the virtual machine.

Alternatively, select the Collapse Snapshots check box to collapse the template disk and virtual disk into a single disk. The export of the virtual machine begins.

The virtual machine displays in Compute Virtual Machines with an Image Locked status while it is exported. Depending on the size of your virtual machine hard disk images, and your storage hardware, this can take up to an hour.

Click the Events tab to view progress. You can export a virtual machine to a data domain to store a clone of the virtual machine as a backup. When you export a virtual machine that is dependent on a template, the target storage domain should include that template. When you create a virtual machine from a template, you can choose from either of two storage allocation options:.

Clone : The virtual machine is not dependent on the template. The template does not have to exist in the destination storage domain. Thin : The virtual machine is dependent on the template, so the template must exist in the destination storage domain. Optional Check Collapse snapshots to export the virtual machine without any snapshots. When you move a disk from one type of data domain another, the disk format changes accordingly. For example, if the disk is on an NFS data domain, and it is in sparse format, then if you move the disk to an iSCSI domain its format changes to preallocated.

This is different from using an export domain, because an export domain is NFS. The virtual machine appears with an Image Locked status while it is exported. When complete, the virtual machine has been exported to the data domain and appears in the list of virtual machines. You have a virtual machine on an export domain. Before the virtual machine can be imported to a new data center, the export domain must be attached to the destination data center.

Click Storage Domains and select the export domain. The export domain must have a status of Active. Select the Collapse Snapshots check box to remove snapshot restore points and include templates in template-based virtual machines.

Click the virtual machine to be imported and click the Disks sub-tab. From this tab, you can use the Allocation Policy and Storage Domain drop-down lists to select whether the disk used by the virtual machine will be thinly provisioned or preallocated, and can also select the storage domain on which the disk will be stored. An icon is also displayed to indicate which of the disks to be imported acts as the boot disk for that virtual machine.

The Import Virtual Machine Conflict window opens if the virtual machine exists in the virtualized environment. Import as cloned and enter a unique name for the virtual machine in the New Name field. Optionally select the Apply to all check box to import all duplicated virtual machines with the same suffix, and then enter a suffix in the Suffix to add to the cloned VMs field. During a single import operation, you can only import virtual machines that share the same architecture.

If any of the virtual machines to be imported have a different architecture to that of the other virtual machines to be imported, a warning will display and you will be prompted to change your selection so that only virtual machines with the same architecture will be imported.

If you are importing a virtual machine from an imported data storage domain, the imported storage domain must be attached to a data center and activated. For each virtual machine in the Import Virtual Machine s window, ensure the correct target cluster is selected in the Cluster list. Map external virtual machine vNIC profiles to profiles that are present on the target cluster s :. If multiple target clusters are selected in the Import Virtual Machine s window, select each target cluster in the Target Cluster drop-down list and ensure the mappings are correct.

If a MAC address conflict is detected, an exclamation mark appears next to the name of the virtual machine. Mouse over the icon to view a tooltip displaying the type of error that occurred. Alternatively, you can select the Reassign check box per virtual machine. If there are no available addresses to assign, the import operation will fail.

The imported virtual machines no longer appear in the list under the VM Import tab. Import virtual machines from a VMware vCenter provider to your oVirt environment. You can import from a VMware provider by entering its details in the Import Virtual Machine s window during each import operation, or you can add the VMware provider as an external provider, and select the preconfigured provider during import operations.

The virt-v2v package is not available on the ppc64le architecture and these hosts cannot be used as proxy hosts. The virt-v2v package must be installed on at least one host, referred to in this procedure as the proxy host. Local storage is not supported. This image includes the guest tools that are required for migrating Windows virtual machines. The virtual machine must be shut down before being imported. Starting the virtual machine through VMware during the import process can result in data corruption.

An import operation can only include virtual machines that share the same architecture. If any virtual machine to be imported has a different architecture, a warning appears and you are prompted to change your selection to include only virtual machines with the same architecture.

Click More Actions and select Import. This opens the Import Virtual Machine s window. If you have configured a VMware provider as an external provider, select it from the External Provider list.

Verify that the provider credentials are correct. If you did not specify a destination data center or proxy host when configuring the external provider, select those options now. If you have not configured a VMware provider, or want to import from a new VMware provider, provide the following details:.

Select from the list the Data Center in which the virtual machine will be available. Enter the IP address or fully qualified domain name of the host from which the virtual machines will be imported in the ESXi field.

Enter the name of the data center and the cluster in which the specified ESXi host resides in the Data Center field. If not, clear the option. The user must have access to the VMware data center and ESXi host on which the virtual machines reside. Select a host in the chosen data center with virt-v2v installed to serve as the Proxy Host during virtual machine import operations. This host must also be able to connect to the network of the VMware vCenter external provider.

Click Load to list the virtual machines on the VMware provider that can be imported. Select one or more virtual machines from the Virtual Machines on Source list, and use the arrows to move them to the Virtual Machines to Import list. Click Next. If required, you can change the driver type to VirtIO manually after the import. To change the driver type after a virtual machine has been imported, see Editing network interfaces.

If the network device uses driver types other than e or rtl, the driver type is changed to VirtIO automatically during the import. The Attach VirtIO-drivers option allows the VirtIO drivers to be injected to the imported virtual machine files so that when the driver is changed to VirtIO, the device will be properly detected by the operating system. Select the Clone check box to change the virtual machine name and MAC addresses, and clone all disks, removing all snapshots.

If a virtual machine appears with a warning symbol beside its name or has a tick in the VM in System column, you must clone the virtual machine and change its name. Click each virtual machine to be imported and click the Disks sub-tab. Use the Allocation Policy and Storage Domain lists to select whether the disk used by the virtual machine will be thinly provisioned or preallocated, and select the storage domain on which the disk will be stored.

If you selected the Clone check box, change the name of the virtual machine in the General sub-tab. Click Compute Clusters. You can export a virtual machine to a specific path or mounted NFS shared storage on a host in the oVirt data center.

Enter the absolute path to the export directory in the Directory field, including the trailing slash. You can import the file from any oVirt Node in the data center. The import process uses virt-v2v. Only virtual machines running operating systems compatible with virt-v2v can be successfully imported. Ensure that it has sufficient space. Select the virtual machine from the Virtual Machines on Source list, and use the arrows to move it to the Virtual Machines to Import list.

Select the virtual machine, and on the General tab select the Operating System. Import virtual machines from Xen on Enterprise Linux 5 to your oVirt environment. The virt-v2v package must be installed on at least one host referred to in this procedure as the proxy host. Enterprise Linux hosts must be Enterprise Linux 7.

If the drivers are not installed, the virtual machine may not boot after import. If you are not using VirtIO drivers, review the configuration of the virutal machine before first boot to ensure that VirtIO devices are not being used. Shut down the virtual machine. Starting the virtual machine through Xen during the import process can result in data corruption.

Due to current limitations, Xen virtual machines with block devices do not appear in the Virtual Machines on Source list. They must be imported manually. The target storage domain must be a file-based domain. Due to current limitations, specifying a block-based domain causes the V2V operation to fail. If a virtual machine appears with a warning symbol beside its name, or has a tick in the VM in System column, select the Clone check box to clone the virtual machine.

Cloning a virtual machine changes its name and MAC addresses and clones all of its disks, removing all snapshots. Attach an export domain. Import the virtual machine into the destination data domain. See Importing the virtual machine from the export domain for details. Import virtual machines from KVM to your oVirt environment.

You must enable public key authentication between the KVM host and at least one host in the destination data center this host is referred to in the following procedure as the proxy host. Starting the virtual machine through KVM during the import process can result in data corruption.

Optionally, select the Collapse Snapshots check box to remove snapshot restore points and include templates in template-based virtual machines. Optionally, select the Clone check box to change the virtual machine name and MAC addresses, and clone all disks, removing all snapshots. Use the Allocation Policy and Storage Domain lists to select whether the disk used by the virtual machine will be thin provisioned or preallocated, and select the storage domain on which the disk will be stored.

If you selected the Clone check box, change the name of the virtual machine in the General tab. This image is a virtual machine snapshot with a preconfigured instance of Enterprise Linux installed. You can configure this image with the cloud-init tool, and use it to provision new virtual machines. This eliminates the need to install and configure the operating system and provides virtual machines that are ready for use.

Create a new virtual machine and attach the uploaded disk image to it. See Creating a Linux virtual machine. Optionally, use cloud-init to configure the virtual machine. Optionally, create a template from the virtual machine. You can generate new virtual machines from this template. See Templates for information about creating templates and generating virtual machines from templates.

Live migration provides the ability to move a running virtual machine between physical hosts with no interruption to service. The virtual machine remains powered on and user applications continue to run while the virtual machine is relocated to a new physical host. Storage and network connectivity are not altered. You can use live migration to seamlessly move virtual machines to support a number of common maintenance tasks. Your oVirt environment must be correctly configured to support live migration well in advance of using it.

At a minimum, the following prerequisites must be met to enable successful live migration of virtual machines:. The source and destination hosts are members of the same cluster, ensuring CPU compatibility between them. The source and destination hosts have access to the data storage domain on which the virtual machine resides.

Live migration is performed using the management network and involves transferring large amounts of data between hosts. Concurrent migrations have the potential to saturate the management network. For best performance, create separate logical networks for management, storage, display, and virtual machine data to minimize the risk of network saturation.

Add both vNICs as slaves under an active-backup bond on the virtual machine, with the passthrough vNIC as the primary interface. The following steps are provided only as a Technology Preview.

Hotplug a network interface with the failover vNIC profile you created into the virtual machine, or start a virtual machine with this network interface plugged in. The virtual machine has three network interfaces: a controller interface and two secondary interfaces.

The controller interface must be active and connected in order for migration to succeed. For automatic deployment of virtual machines with this configuration, use the following udev rule:.

This udev rule works only on systems that manage interfaces with NetworkManager. This rule ensures that only the controller interface is activated. Live virtual machine migration can be a resource-intensive operation. To optimize live migration, you can set the following two options globally for every virtual machine in an environment, for every virtual machine in a cluster, or for an individual virtual machine. The Auto Converge migrations and Enable migration compression options are available for cluster levels 4.

For cluster levels 4. You can change these parameters when adding a new migration policy, or by modifying the MigrationPolicies configuration value. The Auto Converge migrations option allows you to set whether auto-convergence is used during live migration of virtual machines. Large virtual machines with high workloads can dirty memory more quickly than the transfer rate achieved during live migration, and prevent the migration from converging.

Auto-convergence capabilities in QEMU allow you to force convergence of virtual machine migrations. The Enable migration compression option allows you to set whether migration compression is used during live migration of the virtual machine. This feature uses Xor Binary Zero Run-Length-Encoding to reduce virtual machine downtime and total live migration time for virtual machines running memory write-intensive workloads or for any application with a sparse memory update pattern.

Click Compute Clusters and select a cluster. All files or symbolic links in that directory will be executed. The executing user on Linux systems is ovirtagent. If the script needs root permissions, the elevation must be executed by the creator of the hook script.

The destination host for each virtual machine is assessed as the virtual machine is migrated, in order to spread the load across the cluster. From version 4. The Engine automatically initiates live migration of virtual machines in order to maintain load-balancing or power-saving levels in line with scheduling policy. Specify the scheduling policy that best suits the needs of your environment.

You can also disable automatic, or even manual, live migration of specific virtual machines where required. However, this can be changed to Allow Manual and Automatic mode if required. Special care should be taken when changing the default migration setting so that it does not result in a virtual machine migrating to a host that does not support high performance or pinning.

You can also disable manual migration of virtual machines by setting the virtual machine to run only on a specific host.

The ability to disable automatic migration and require a virtual machine to run on a particular host is useful when using application high availability products, such as Red Hat High Availability or Cluster Suite. Explicitly assigning a virtual machine to a specific host and disabling migration are mutually exclusive with oVirt high availability. If the virtual machine has host devices directly attached to it, and a different host is specified, the host devices from the previous host will be automatically removed from the virtual machine.

Select Allow manual migration only or Do not allow migration from the Migration Options drop-down list. A running virtual machine can be live migrated to any host within its designated host cluster.

Live migration of virtual machines does not cause any service interruption. Migrating virtual machines to a different host is especially useful if the load on a particular host is too high. For live migration prerequisites, see Live migration prerequisites.

Select Select Host Automatically so that the virtual machine migrates to the host that offers the best performance. When you place a host into maintenance mode, the virtual machines running on that host are automatically migrated to other hosts in the same cluster. You do not need to manually migrate these virtual machines. Use the radio buttons to select whether to Select Host Automatically or to Select Destination Host , specifying the host using the drop-down list.

When the Select Host Automatically option is selected, the system determines the host to which the virtual machine is migrated according to the load balancing and power management rules set up in the scheduling policy. During migration, progress is shown in the Migration progress bar. Once migration is complete the Host column will update to display the host the virtual machine has been migrated to.

The load balancing process runs every minute. Hosts already involved in a migration event are not included in the migration cycle until their migration event has completed. When there is a migration request in the queue and available hosts in the cluster to action it, a migration event is triggered in line with the load balancing policy for the cluster. You can influence the ordering of the migration queue by setting the priority of each virtual machine; for example, setting mission critical virtual machines to migrate before others.

Migrations will be ordered by priority; virtual machines with the highest priority will be migrated first. A virtual machine migration is taking longer than you expected.

Select the migrating virtual machine. It is displayed in Compute Virtual Machines with a status of Migrating from. Click More Actions , then click Cancel Migration. When a virtual server is automatically migrated because of the high availability function, the details of an automatic migration are documented in the Events tab and in the engine log to aid in troubleshooting, as illustrated in the following examples:. Failed to start Highly Available VM.

Attempting to restart. High availability is recommended for virtual machines running critical workloads.

A highly available virtual machine is automatically restarted, either on its original host or another host in the cluster, if its process is interrupted, such as in the following scenarios:.

A highly available virtual machine is not restarted if it is shut down cleanly, such as in the following scenarios:. With storage domains V4 or later, virtual machines have the additional capability to acquire a lease on a special volume on the storage, enabling a virtual machine to start on another host even if the original host loses power.

The functionality also prevents the virtual machine from being started on two different hosts, which may lead to corruption of the virtual machine disks.
