Don't know why, but without the VirtPreview repo I get the following error:

"libvirtError: POST operation failed: xend_post: error from xen daemon:

If I run

$ virt-viewer rubis-web

where "rubis-web" is the name of my domU

I get a dialog box with this error message

"Unable to connect to libvirt with URI [none] "

and on the console terminal I get this message

** (virt-viewer:4506): WARNING **: Couldn't connect to accessibility bus:
Failed to connect to socket /tmp/dbus-giWEeisA4Z: Connection refused

(but I don't know if they are related, because the above message is only a
warning, while the former is an error.)

Instead, if I use a VNC viewer (actually, tigervnc) it works without

$ vncviewer

If I look in the XML of my domU:

$ virsh dumpxml rubis-web

I can see the entry for VNC:

    <graphics type='vnc' port='5900' autoport='yes' keymap='en-us'/>

I see
