I concur with mavrick and continuum. Does anyone know of a way to raise this issue? Has anyone tried upgrading recently?

So I also had this problem, for the time I've reverted all the way back to UnRAID 6.9.2 which exhibits none of these issues. I have both ESXi running as a Guest on UnRAID and a Windows 10 VM that runs VMware Workstation (where my vCenter is installed). I went through the trouble spinning up a Windows 11 VM and testing compatibility in there as well. The primary behavior that was noticed is that this error message when running ESXi 7 and VMware Workstation 16.5 is along the lines of "vcpu0:invalid VMCB". I tested VMware Workstation 17 as well and "AMD-V is supported by the platform, but is implemented in a way that is incompatible. " After some searching it turns out that pre-2011 AMD's version of AMD-V botched the VMCB flags and didn't include the proper virtualization parameters. My best guess at the moment is that the QEMU version in UnRAID 6.11.x is for some reason implementing an extremely outdated version of AMD-V that is getting passed through...when they were doing it properly before. No amount of XML flags seems to fix the issue. Can anyone chime in on QEMU regression changes?
