Those two are very different. 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.
Does boot_xen.py actually boot *Xen*? 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.
Yes, so the tag "guest:xen" is correct.
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?
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.
