Proxmox Migrate Intel(R) Xeon(R) Gold 6148 > Intel(R) Xeon(R) CPU E5-2660

[LLevon]

Hello, I am having a migration problem to another cluster node, when I migrate a vm from a proxmox with Intel(R) Xeon(R) Gold 6148 processor to another proxmox of the Intel(R) Xeon(R) CPU E5-2660 cluster, after the migration is complete, I have to restart the vm, because it hangs.

I've never tested something like this, my hardware across the cluster is very similar, but could it be that the CPU features are extremely different causing the system to hang?

in your VM, the CPU configuration is "host" or "KVM Processor" ?

Moving to 6.x kernel seems to be the prevalent suggested solution

Thanks, after upgrading the kernel to 6.x worked the migration of VMs
