ConVirt

it looks ok for running DomUs.
The information pane lacks Network and Disks, but they don't seem to be in the tree either.

Loading the corresponding config file fails with:
"FAILED: Invalid File: iteration over non-sequence"

Furthermore Xen3.1.0 seems to have a bug with the VNC display number. It is _not_ the domain id, but it simply uses the first available free one.
Workaround or maybe the correct way to retreive the port:
xenstore-read /local/domain/0/backend/vfb/$DOMID$/0/location

This will give you the host and port of the vnc server belonging to this domain. (e.g.: localhost:5900)
