Here's some nerd shit right here:
Booted to Linux, using virsh/qemu/kvm to run a slightly customized (XML was edited to make it pretend to be a particular CPU) Win10 virtual machine that's able to run Hyper-V, so I'm running a VM inside a VM (yo dawg). Performance is actually acceptable.
I've wanted to do basically this for almost fifteen years now but the hardware and software available to me was just never there. #feelsgoodman
This is a practice run; I've been thinking about doing this in anger on my new work PC. Base OS being Xubuntu 20.04, running one or two Win10 VMs for different tasks as-needed, and potentially MacOS in another VM. One of the Win10 VMs would be for making up new Windows install images, best handled with Hyper-V VMs because the workflow is actually really good.
