That seems like a problem in the Debian packaging system, not in
libvirt. I double-checked with the upstream folks, and the install
rules for Wireshark plugin doesn't have /*/ in there.

Note: You don't even have to build the versions from 'Buster', which are
quite new. Just the slightly more conservative libvirt 3.2.0 and QEMU
2.9.0 -- only if it's possbile.

Sure, can use the 3.0.0 (& QEMU 2.8.0), instead of 3.2.0, as we don't
want to "penalize" (that was never the intention) distros with slightly
That said ... I just spent comparing the release notes of libvirt 3.0.0
and libvirt 3.2.0. By using libvirt 3.2.0 and QEMU 2.9.0, Debian users
will be spared from a lot of critical bugs (see all the list in ) in
CPU comparision area.
-- Release of libvirt-3.2.0
-- Release of libvirt-3.0.0
