Clustering and Live Migration
Q. Is Clustering and Live Migration included in Hyper-V Server 2008 R2? A. Yes. Hyper-V Server 2008 R2 includes live migration and host clustering and Hyper-V Server 2008 R2 will be available for free. Q. Up to how many nodes on a cluster does Live Migration support? A. Live Migration is supported on up to 16 node failover clusters. Q. What is the maximum number of supported VMs per node? A. For production deployment, up to 64 VMs per node are supported. Customers must plan for adequate capacity when a failover occurs and VMs from the failed host are brought online on different nodes of the cluster. Q. Will Live Migration work on with a cluster of mixed AMD and Intel host nodes? A. For Live Migration to work, all cluster nodes must have processors from the same processor vendor, for example Intel or AMD. Q. Assuming host nodes have a virtualization capable processor from the same manufacturer, can I migrate a VM from a host using an older processor to a host with a newer processor? A. It is highly recommended to use identical processors on all nodes of a cluster using Quick or Live Migration. Live Migration or Quick Migration will work moving VMs from and older processor to a newer processor. However, to migrate a VM from a newer processor to an older processor, the VM must be turned off and restarted after moving the VM. A new functionality is the ³Processor Compatibility´ option. This functionality can be enabled for VMs to allow both Live Migration and Quick Migration from newer to older processors from the same manufacturer. The setting is under VM settings > Processor > ³Migrate to a physical computer with a different processor version´. You can live migrate or quick migrate a running VM from an older processor to new processor and back without the ³Processor Compatibility´ option as long as the VM is running all the time. Q. Are there any new tools included with Hyper-V Server R2 to help manage the server? A. A new server configuration script is available in the Hyper-V Server 2008 R2. Type sconfig at the command line to start the server configuration utility.
