The last version bump was in "Pike" release (commit: b980df0,
11-Feb-2017), and we didn't do any bump during "Queens".  So it's time
to increment the versions (which will also makes us get rid of some
backward compatibility cruft), and pick future versions of libvirt and
QEMU.                                          

As it stands, during the "Pike" release the advertized NEXT_MIN versions        
               
were set to: libvirt 1.3.1 and QEMU 2.5.0 -- but they weren't actually          
               
bumped for the "Queens" release.  So they will now be applied for the           
               
"Rocky" release.  (Hmm, but note that libvirt 1.3.1 was released more           
               
than 2 years ago[1].)                          

While at it, we should also discuss about what will be the NEXT_MIN             
               
libvirt and QEMU versions for the "Solar" release.  To that end, I've           
               
spent going through different distributions and updated the                     
               
DistroSupportMatrix Wiki[2].                   

Taking the DistroSupportMatrix into picture, for the sake of discussion,
how about the following NEXT_MIN versions for "Solar" release:                  
               

(a) libvirt: 3.2.0 (released on 23-Feb-2017)   

    This satisfies most distributions, but will affect Debian "Stretch",        
               
    as they only have 3.0.0 in the stable branch -- I've checked their
    repositories[3][4].  Although the latest update for the stable
    release "Stretch (9.4)" was released only on 10-March-2018, I don't
    think they increment libvirt and QEMU versions in stable.  Is
    there another way for "Stretch (9.4)" users to get the relevant
    versions from elsewhere?                   

(b) QEMU: 2.9.0 (released on 20-Apr-2017)      

    This too satisfies most distributions but will affect Oracle Linux
    -- which seem to ship QEMU 1.5.3 (released in August 2013) with
    their "7", from the Wiki.  And will also affect Debian "Stretch" --
    as it only has 2.8.0

Can folks chime in here?
