    Nested virtualization suddenly doesnt work

    *Update* I found out, that changing CPU from host to any other CPU type allows the vm to install docker and hyper V. Why is this the case? I need the vm to use CPU host, but this no longer works

    Nested virtualization suddenly doesnt work

    I havnt followed the known issues, no. However the problem is not starting the VM, rather that enabling windows hyper V results in a crash. Does the cpu flag hv-evmcs need to be on for virtualization to work? Because then i cannot start the vm

    PCI passthrough Error code 43

    Hello Darin, the fix which worked for me, was going into the bios and changing a CPU option from IGD to PEG. I have an intel motherboard, but i would guess the same counts for a amd :)

    PCI passthrough Error code 43

    FIXED!!! By some amazing help from jimnordb aka. SilentSpy, we were able to find out, that a bios option regarding CPU specifications needed to be changed from IGD to PEG. This enables my GPU to be used seperatly and worked like a charm.
