In the style of the other one re lvnc console in lenny;

        so, the tools to pin this down.

                See tracelog-centos-qemu.log.   This is unexpected.
Why is a qemu install pulling in  xenUnifiedDomainLookupByName?  I don't know, I hopw someone else does.
It may be correct, but it seems totally out of place.  How would qemu do a hvm install if xen were not installed?
Anyway.

strace logs are no easy reading.  Is there a short route to learning how to read strace??????

Could you please tell me how to utilise dbg   using file command for executable.  I can't figure it out.  I just get no executable file trying to run these libvirt & python scripts through gdb.

I should post all this in gentoo.  It all applies.
  It looks more looks xen-utils, do you think?
