Hey Dan, This commit changes the behavior of LIBVIRT_DEBUG=1 libvirtd: $ git show 7022b09111d4322d21396a70d58320a9ad773962 commit 7022b09111d4322d21396a70d58320a9ad773962 Author: Daniel P. Berrange <berrange(a)redhat.com&gt; Date: Thu Sep 27 13:13:09 2012 +0100 Automatically enable systemd journal logging Probe to see if the systemd journal is accessible, and if so enable logging to the journal by default, rather than stderr (current default under systemd). It still prints some output to stderr but it's extremely limited compared to before. Surprised me at least, but I didn't dig too deeply for a solution. Thanks, Cole
