One runs on Xen, the other on KVM. Do we want to use the same tag for both?

One runs on Xen, the other on KVM. Do we want to use the same tag for both? My understanding is, - boot_xen.py runs Xen on TCG - kvm_xen_guest.py runs Xen on KVM so both runs Xen guests. Alex, is that incorrect?

Does boot_xen.py actually boot *Xen*? And presumably at least one Xen guest *within* Xen? kvm_xen_guest.py boots a "Xen guest" under KVM directly without any real Xen being present. It's *emulating* Xen. They do both run Xen guests (or at least guests which use Xen hypercalls and *think* they're running under Xen). But is that the important classification for lumping them together?

And presumably at least one Xen guest *within* Xen? I'll let Alex confirm, but yes, I expect Xen guest within Xen guest within TCG. So the tags "accel:tcg" (already present) and "guest:xen". > kvm_xen_guest.py boots a "Xen guest" under KVM directly without any real Xen being present. It's *emulating* Xen.

But is that the important classification for lumping them together? The idea of AVOCADO_TAGS is to restrict testing to what you want to cover. So here this allow running 'anything that can run Xen guest' in a single command, for example it is handy on my macOS aarch64 host.
