Hello,

Here is the thing, It is a home lab with 3 proxmox nodes and ceph, 2 nodes are with N100 cpu and a last one with a N5100.
There is a windows2022server running on ceph storage I would like to be able to move around the different nodes.
I followed a nice tutorial to install the windows guest :
https://pve.proxmox.com/wiki/Windows_2022_guest_best_practices
Performance was satisfying. However, when live migrating from N100host to N5100host the VM crashes (when processor is set to "host").
So I went to set the processor type to qemu64, the performance was less satisfying, but live migration worked.

I was wondering if someone around here had made recent tests or had a particularly good insight on which processor type would give the best performance while still allow live migration?

Have a nice day,
-Phil

I have no experience with those CPUs, but in general I would try with the current default: x86-64-v2-AES.
