I'm now experimenting with different settings and found way to enable nested virtualization with host cpu type and no performance penalty. Disabling aspm in bios does fix it for win11 guest. (proxmox, hyperv enable= d) Further testing is required, so anyone having this issue can contribute by testing other guest operating systems. For now it's best solution until fix from AMD arrives. Unless its irreparable with just microcode update... --=20 You may reply to this email to add a comment. You are receiving this mail because: You are watching the assignee of the bug.=
