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. 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"

dumping the XML of the config like that won't work.
