I have a AMD Ryzen 1700 on Ubuntu 18.04. I have installed a Windows 10 guest under KVM using virt-manager. To be able to do that with the right CPU type ("EPYC" or "EPYC-IBPB"), I had to apply the workaround described here ("options kvm ignore_msrs=1").
Now I'd like to experiment with Docker on the Windows 10 guest. It requires a functioning Hyper-V install. Unfortunately the Hyper-V hypervisor cannot be installed because "The processor does not have second level access translation (SLAT) capabilities".
Weirdly, on a Windows 7 guest I do seem to have nested virtualization enabled (but the Docker Desktop Client only supports Windows 10).
What could be the cause here?
