[You used git send-email incorrectly - when it asks what to use as
in-reply-to, you should hit 'enter' with blank text to create a new
thread, rather than attempting to answer 'y' which threads it to any
other thread that also used the incorrect 'y' as a message id.  Newer
git prevents the use of invalid message ids - so another solution is to
upgrade your git.]

Unfortunately, your patch is incorrect.  When applying it, and
re-running 'make check', I get a failure:

FAIL: virsh-schedinfo
