Xen configuration

Hi all!
I just installed openSuse 11.2. Everything was fine.
Then I installed “Hypervisor and Tolls” in order to create a Solaris 10 OS virtual machine.
Installation of Xen was fine, also. And I can log in Xen console from Grub.
But I don’t know how I must to create the virtual machine. When I try to open the “Virtual Machine Manager” I get:

Unable to open connection to hypervisor URI 'xen:///':
no es posible conectarse con '/var/run/libvirt/libvirt-sock': No existe el fichero o el directorio
Traceback (most recent call last):
  File "/usr/share/virt-manager/virtManager/connection.py", line 456, in _try_open
    None], flags)
  File "/usr/lib/python2.6/site-packages/libvirt.py", line 111, in openAuth
    if ret is None:raise libvirtError('virConnectOpenAuth() failed')

So, I think I must to configure Xen.

Can sombody help me, and guide me?

Thank you, in advance.

Hi, to start virt-manager GUI try to login as root.
