FWIW I was excited about this in 6.0 but never actually got it to work with Hyper-V. It may be a hardware issue on my side (my CPU is ~6 years old and doesn’t support some VM features) but I’ve also seen a lot of other people say that 6.0 changed nothing for them in regards to Hyper-V compatibility.
“Added support for using Hyper-V as the fallback execution core on Windows host, to avoid inability to run VMs at the price of reduced performance“
Is that the workaround you’re looking for? It seems like it comes at a cost, but workarounds often do.
