For one thing you pretty much never want to run plain 'su' if trying to launch
a modern desktop app. Use 'su -', which invokes a full login shell, giving
root it's own environment, etc. This has caused issues with virt-manager in
the past

Also, are you at the physical machine, or running over ssh ?

Try running virt-manager --debug and see what output it shows when it hangs,
maybe there's some obvious error that needs fixing.
