it looks like you logged in as yourself, then did a sudo su - (which
is normally how things should be done)
(or maybe even just a sudo su).   there are a couple things you can do
to get around that; I think the most expedient is to run (as yourself)
you at it you> sudo virt-manager

other options include (although I'm sure I'll get flames for it) log
in directly as root or set your ID to have the permissions to do all
that's needed to run virt-manager, or make sure your X config allows
tcp connections and use 'xhost +localhost', then export
DISPLAY=localhost:0 as root user (probably; you might need to check
your DISPLAY settings as your own ID before -- env | egrep -i display)

this is just my guess, though.
