Looking through the changelogs and the content of the rest of our cloud
images, I think the hyperv-daemons from 5.10 should be OK.  We're
installing that version on all our amd64 cloud images (including the
-backports image), so the only potential issues I can see are:

  * There's some arch-specific issue impacing hyperv-daemons for arm64,
  * There's the possibility for confusion among the current users of our
    arm64 bullseye-backports images, as they've previously contaned the
    6.1 version of that package.

I think I'm OK with the risk associated with those issues, and am in
favor of doing the most basic work to enable the 5.10 hyperv-daemons
binary package.

Thanks
