I had LIBVIRT_DEBUG=1 exported and ran libvirtd --verbose from the command line. My /etc/libvirt/libvirtd.conf had: log_outputs="3:syslog:libvirtd 1:file:/tmp/libvirtd.log" But I didn't get any debug messages. > % cat /var/log/libvirt/qemu/$guest.log Nothing in here.

Trying to get some more info out of libvirt as well.
