I think the first reason why this dependency was brought up during last
friday was the fact that when qemu gets upgraded to the binaries built
against 4.11, but the 4.8 hypervisor is still running, it's no longer
possible to start a new domU which uses qemu.

Also note that this is not a new problem, it has always been like this.

However, in the "upgrade notes" that we should have somewhere we must
strongly recommend to not do anything else than shutting down or saving
the running domUs and rebooting the host machine ASAP after upgrading
the Xen packages.
