Hi!
I recently ran into a problem when connecting to libvirtd 6.9.0 on Debian unstable
and trying to import an existing image with Windows 7.
Upon finishing the wizard and starting the instance, the import process fails
with the following error message:
Unable to complete install: 'internal error: qemu unexpectedly closed the monitor'
Traceback (most recent call last):

libvirt.libvirtError: internal error: qemu unexpectedly closed the monitor
Since this error message is rather generic, I don't know where to start debugging.
Does anyone know how to increase verbosity here to get an error message that might be
more helpful?
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. 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"
