Done.

 
and then try to start a container again. The container log
file above should now get much more verbose data (i don't
care about the log output from libvirtd itself - just the
container log file).

The log is large to place inline in an email (32K), so I posted it (no expiration) to pastebin.  But below are the juicy bits.  If you want the entire log in the email, I will resend it.
