Short version:
Anyone changed CPU type on a Windows 11 VM and know how to get it to stop crashing?
Long version:
I set up a Windows 11 VM in VE 8.2.2 and didn't notice the CPU type was set to x86-64-v2 instead of host. It was set to single processor with 8 cores. Everything was running great, Nvidia GPU passed through, got many things set up, and then ran into something that wouldn't run due to lack of AVX. This is when I realized the problem. I shut down the VM, set the CPU to "host" (a Ryzen 9 3900X), and started it up again.
Everything seemed to be working great. AVX supported, things running. Proxmox showed no issues. However, when logged into the VM I noticed it rebooting every few minutes. Checking event log it's a bugcheck error 0x113 which appears to be something with DirectX. I updated the Nvidia drivers. Same issue. I ran DISM to attempt system repair (5 times thanks to the constant reboots) but it finally completed with no errors. Still crashing.
Changing the cpu type back to x86-64-v2 seems to have stabilized the VM again at the cost of AVX. Does anyone know what to do to let me switch the CPU type to "host" without crashes? I really really don't want to rebuild the VM from scratch at this point.
