Processor-specific feature not supported Rating Explanantion error message on migration a VM with SCVMM 2008 R2

When you try to migrate a Virtual Machine with System Center Virtual Machine Manager 2008 R2 from one server to another you get a processor-specific feature not supported Rating Explanantion error message:

“virtual machine ServerName is using processor-specific features not supported on host vmhost.domain.local To allow for migration of this virtual machine to a server with a different processor, modify the virtual machine settings to limit the processor features used by the virtual machine.”

This message wil appear when you try to move between to different hardware processor types. If you want to migrate virtual machines between different processor types you can check the following option within the virtual machine properties. Choose Hardware Configuration, Processor and check “Allow migration to a virtual machine host with a different processor”

This option can only be set when the virtual machine is stopped. So shutdown the virtual machine, change the setting and start the virtual machine, now you are able to migrate the server using System Center Virtual Machine Manager. It would be wise to enable this option by default if you want to create a high available solution between servers with different hardware processor types.
