Comment 3 for bug 1971315

Xen check in more detail:
- after all the reduction in the past all real delta left is to depend on qemu-system-x86-xen instead of qemu-system-x86

Debian has followed that idea with some variation:
- xen-utils-4.16: depends on qemu-system-xen (>> 1:7.0+dfsg-6~) [amd64]
- the 4.16.1-1 entry in [1] talks about it

TODO (for xen):
- our merge of qemu will follow the Debian change to establish qemu-system-xen (naming reason is that 4.16 stopped doing i386 xen support anyway)
- We will need a transitional qemu-system-x86-xen -> qemu-system-xen
- once qemu 7.0 is in Kinetic we can sync xen 4.16.1-1
