Sorry for not making myself clear.  That looks like a bug, but it will
be harder to find out the root cause.  Could you file a bug report for
that and attach the logs which have the command lines in them (as below)
and also output of the virt-install command you started with added
--debug parameter?  That would help us track the issue and work on it.

Thanks,
Martin
