We've a shared beefy Threadripper workstation in my lab that has a boatload of RAM and cores to spare. We set up Qemu + KVM in order to run a big Windows VM that we use mainly for MS Office via RDP connections and when we really need Visual Studio. We also have a FreeBSD and a Aarch64 Linux instance that we use for testing. It's amazing how flexible Qemu is, and how reliable the whole stack can be.
