Description of problem: Running virt-manager does not hide the main virt-manager console.
One less window cluttering desktop would be nice if we can make it use a system tray icon. Could also provide additional functionality with the systray icon too.
Version-Release number of selected component (if applicable):
Systray icon has been upstream since virt-manager-0.8.0, and recently a patch was committed to keep the app running if the systray icon is present but all windows have been closed.
