To be honest the only thing which wonders me is, why some people have downplayed the issue when many others showed enough evidence. And that includes also Proxmox stuff. If you do not know what I mean, read the whole thread.
Do you know if there is a way to confirm if AVIC is working in the guest?
This is something I was trying to figure out over recent days, I can only find ways to confirm its loaded in amd_kvm module and if its present on host CPU, but not ways to confirm its active in the guest.
