Hyper-V R2 “there was an error checking for virtual machine compatibility on the target node”

 

While initiating a live migration of a running virtual machine under Hyper-V R2 the error message below is displayed:

“there was an error checking for virtual machine compatibility on the target node
The virtual machine <name> is not compatible with the target node <nodename>. Hyper-V has detected that: The virtual machine <name> is not compatible with physical computer <servername>. The virtual machine <name> is currently using an Intel processor, but physical computer <servername> has an Unknown processor.

Solution: make sure Intel Virtualization Technology & Execute Disable Bit (or AMD equivalent) are both enabled on the target Hyper-V server.
