When in Xen Virtual Machine manager, when I attempt to "Open" a console, the VMM flashes up a new window, then vanishes.

Once I get a VM installed and assigned an IP address, it is no problem connecting with VNC, but if I cannot start a VM for any reason, I cannot get a console in order to debug the problem.

xm vncviewer ID (ID # from 'vm list') does work. However, on running VMs, both Windows and Linux, I cannot Open from the VMM.

Open SuSE 11.1, fully patched.
