[virt-tools-list] Virt-manager just sits at Connecting...

[Greg Teiber]

I'm using VNC to get to the desktop on a physical server.  

I tried it with su - and no joy.  So I tried virt-manager --debug  

I got back a couple pages of this: 

" Traceback (most recent call last):
  File "/usr/share/virt-manager/virtManager/baseclass.py", line 135, in wrap_func
    self.disconnect(id_list[0])
  File "/usr/share/virt-manager/virtManager/baseclass.py", line 96, in disconnect
    ret = GObject.GObject.disconnect(self, handle)
  File "/usr/lib64/python2.7/site-packages/gi/overrides/GObject.py", line 429, in wrapper
    return func(_get_instance_for_signal(obj), *args, **kwargs)
  File "/usr/lib64/python2.7/site-packages/gi/types.py", line 113, in function
    return info.invoke(*args, **kwargs)
TypeError: argument instance: Expected GObject.Object, but got PyCObject"

That's an obvious problem, but I'm not sure what direction to go in repairing it.

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.
