Re: [libvirt] Re: [Qemu-devel] Changing the QEMU svn VERSION string

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. 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.
The Linux kernel was guilty of mixing up later and earlier version
suffixes like this. With Linux this is a bit more important because
it changes a lot between versions, so some apps do need fine-grained
version checks to workaround bugs or avoid buggy features. Maybe that
won't even happen with QEMU and libvirt working together.
