I've also backported this to v0.10.2-maint, since that is the branch
used for F18 libvirt.  I had some merge conflicts to resolve, so I'll
reply to this message with the actual patches that I pushed, if anyone
is interested in double-checking them.  I went ahead and pushed the
backports under the build-breaker rule (as it was interfering with me
backporting some other patches to v0.10.2-maint on my F18 box).
