In system mode, the daemon runs as root.  It is the preferable option,
default when connecting as root, supports more features than session mode.

In session mode, the daemon runs under the user who connects, some

I will direct you to http://libvirt.org/drvqemu.html where more on that
can be found.

Not that's interesting!  What's the info in the logs now when you can
access them?  (my previous explanation was aimed at system mode)
