Hyper-V Live Migration Between AMD EPYC 7F72 and AMD EPYC 74F3

Hello,

 

i would like to ask about some help with diagnose my problem with live migration virtual machine in hyper-v cluster between two servers - one have processor AMD EPYC 74F3 and another have processor AMD EPYC 7F72. I got error when i want to live migration some vms between this two servers:

 

"(Event Id : 24004 " The virtual machine 'ABC' is using processor-specific features not supported on physical computer 'ABC'. To allow for migration of this virtual machine to physical computers with different processors, modify the virtual machine settings to limit the processor features used by the virtual machine. (Virtual machine ID XYZ)"

 

 

These servers are Dell R6525 and i contact with Dell support but they told me, thath this is a OS problem and they can't help me. I'm looking for some advice, that may help me to resolve my problem and confirm that this is possible or not.

 

Some details:

 

Dell Servers R6525 with Windows Server 2019 Datacenter

Firts server: AMD EPYC 74F3 - currently BIOS Version 2.8.4 (previous was 2.15.2 - i downgraded bios to check with another version)

Secondary server: AMD EPYC 7F72 - currently BIOS Version 2.15.2 (i check too on version 2.8.4 and this doen't work)

 

Another server on cluster have processor AMD APYC 7F72 and bios version 2.8.4 , migration between servers with the same processor are working well.

    Hi  

     

     

    To transfer the virtual server to a host with different processors "Migration to a physical computer with a different processor version " option needs to be ticked.
