[Fedora-xen] error when trying to connect with virt-manager

[Fischer, Anna]

The log says:

Wed, 22 Nov 2006 12:17:44 ERROR    Unable to open connection to
hypervisor URI 'xen': socket.gaierror (-2, 'Name or service not known') 

"virsh list" runs perfect on my system. Furthermore, a strange thing is
that while this error message window is shown when virt-manager starts
up, I can see in the background (virt-manager GUI is actually loaded
while showing the error message) that virt-manager shows Dom0 and its
CPU usage etc. correctly. So why do I get this error message then and
virt-manager shuts down?
