https://gitlab.com/qemu-project/qemu/-/issues/1031 To wrap up: . enable pass through with additional XML lines You can put these lines just above the end of the /domain line as show below. <qemu:commandline> <qemu:arg value='-cpu'/> <qemu:arg value='host,level=30'/> </qemu:commandline> </domain> From what I read these parameters work with Intel 12th, 13th and 14th (mine) Gen processors. I wrote this post under a different topic weeks ago, sorry about late response.

From my undestanding, so called nested virtualization is possible and it's also supported, regarding the MS Hyper-V... But I also haven't yet found a way to achieve this. Everytime I enable HV functionality inside MS Server 2022, same thing happens. It breaks the VM and it seems like something is totally blocking the CPU cores. Furthermore, I am not trying to find the proper CPU parameters for XML template. So far, w/o success... I have a i9-14900KS and I am trying to find settings based on this CPU. When / IF I find anything, I will let you know.

I have the same problem and I am still looking for a solution to this issue. But, could you please elaborate on why is this a big no-no? I feel like I am missing something. Thanks.

That was like super simple. Never used Active Backup really... I did tested it a bit years ago when it was firstly introduced but was not quite there yet. Maybe it's time to check it more thoroughly again. Thank you for this!
