Thanks Adriano ... I don't think that in my case the problem is with the CPU,
because when I changed from Q35 architecture to PC everything works.
This is the xml used for this OpenBSD vm:

Hi.
I used to run OpenBSD vms using libvirt on Debian and NixOS for quite long
time using both pc and q35 without any problem. Unfortunately the xmls from
libvirt are not easily recoverable at the moment.
Recently I moved to Proxmox and yesterday I upgraded all the machines to
7.6 without any issue. In Proxmox, the cpu type is set to "x86-64-v2-AES”
In case that helps.
Regards,
Adriano
