VM freezes when migrating from node to node

[systemctl]

Hello, we have a cluster with 2 nodes on different hardware - E5-2680 v3 and Silver 4214 .
Any VM that migrates from one to another freezes, all time. We have to reset them.
All VMs have kvm64 processor type, but honestly it doesn't matter, we tried on any processor type and even custom types.

Migration between v3 - v2 ( and vice versa ) or between Silver - Gold works fine.

Any suggestions?

screened VM console just after migration with kernel panic log.

Can you try upgrading to kernel version 5.19 and see if that fixes the issue? We had some issues with 5.15 and live migration, but that was mostly related to AMD CPUs iirc.

Migrating between different CPUs can always be a bit tricky. Would it be an option to shutdown the VM, migrate it, then boot it again? This should work in any case.

FYI, there's also the FPU issue which does affect Intel CPUs: https://forum.proxmox.com/threads/109645/ and is also solved by upgrading to kernel 5.19
