Considering the WIP state of pKVM, my setup is hacky and not that stable. I use QEMU, along with Will'ls pKVM user ABI patches [*] and a couple of hacks added on top to run a normal VM with the protected codepath applied to it, to be able to do some testing and sanity checking. There isn't really any proper way of playing with protected VMs yet.
