The first step would be to look in
/var/log/libvirt/qemu/$guestname.log.
If qemu is encountering some error, it should be logging a message there
before it exits. (unless the error is a segfault; in that case I guess
you'll need to look for a coredump. It will also list exactly the qemu
commandline that was used.
Except for some unrelated warnings, qemu does not emit any error message:

If the message there isn't illuminating enough and you come back
here, it would be helpful
to "bring along" that qemu commandline (and any accompanying error) as well as
the output
of "virsh dumpxml $guestname"
Since libvirt won't create the guest instance in the first place, dumping the XML of
the config
like that won't work. However, it's possible to view the XML from the preview
window in the
machine details:
