Ok, but try to stick to a well-defined rule about what suffix means
"later" or "earlier". In package managers, "1.2.3-rc1" is
typically
seen as a later version than "1.2.3" purely due to syntax.
Fedora typically handles this using a leading zero in the 'release'
component for pre-final versions, like this: app-1.2.3-0.rc1.fc11
(rc/beta) and app-1.2.3-1.fc11 (final). Likewise for snapshots:
app-1.2.3-0.svn${date}.fc11
If you're
consistently meaning "0.11.0-rc1" is earlier than "0.11.0" (final),
that might need to be encoded in libvirt and other wrappers, if they
have any fine-grained version sensistivity such as command line
changes or bug workarounds.
libvirt scans the help text to figure which features are present
(checking for as -drive and -uuid cmd line switches for example).
