Hello,

I have weird situation when I am live migrating VM between two nodes.
Both have AMD cpu but different type.
First node type :

Code: 
CPU(s) 64 x AMD EPYC 7513 32-Core Processor (2 Sockets)
Kernel Version Linux 5.15.60-2-pve #1 SMP PVE 5.15.60-2 (Tue, 04 Oct 2022 16:52:28 +0200)
PVE Manager Version pve-manager/7.2-11/b76d3178

Second node type :
Code: 
CPU(s) 128 x AMD EPYC 7662 64-Core Processor (2 Sockets)
Kernel Version Linux 5.15.60-2-pve #1 SMP PVE 5.15.60-2 (Tue, 04 Oct 2022 16:52:28 +0200)
PVE Manager Version pve-manager/7.2-11/b76d3178

And now !
when I am migrating from second type node to first type - everything works.
when I am migrating from first type to second type - vm suspend.


I can reproduce issue.
here is gui log :

When I select specified CPU , EPYC-MILAN , there was few errors on that second type of CPU

Hi,
what CPU type did you have before selecting EPYC-MILAN? Can you try upgrading to kernel 5.19 and see if the issue persists?

Please post the output of pveversion -v from both nodes and the VM configuration qm config 99998.
