I still think libvirt should work with versions of QEMU/KVM built from svn/git though. I think the only way to do that is for libvirt to relax their version checks to accommodate suffixes in the form major.minor.stable-foo.
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). cheers, Gerd
