Did you also edit $HOME/usr/etc/libvirt/virtlogd.conf?

The problem is that virLogManagerDaemonPath() doesn't consider any configuration
file, so it will always try to connect to LOCALSTATEDIR "/run/libvirt/virtlogd-sock"

This could be fixed, at least partially.  Would you mind creating a bug in our
bugzilla so that we don't lose track of the issue?

Feel free to use:

https://bugzilla.redhat.com/enter_bug.cgi?product=Virtualization%20Tools&component=libvirt

Or even better, get your first contribution by fixing that ;)

Have a nice day,
Martin
