But, on the host server in question, in the /etc/libvirt/libvirtd.conf file there are a few logging options you can change. (the path might be different on non RHEL/Fedora) Just as a test, to see if it helps, you could change the options: #log_level = 3 and # log_outputs="3:syslog:libvirtd" Perhaps change the log_level to something more verbose, like: log_level = 2 And direct all log output to a file somewhere: log_outputs="2:file:/var/log/libvirt/log-testing.log" There's another option "log_filters", but you're probably best to not change that until you know what you want. Suggesting the above, because it might at least point you in the right direction. :) Hope that helps. Regards and best wishes, Justin Clift
