One other curious thing I noticed is that sometimes the console screen
itself (i.e. a monitor attached to the host, and the default terminal
ALT-F1) shows the running VMs without any change, and other times the VMs
are not shown.
It's only the xsconsole on a remote terminal (over ssh) or a local terminal
that always loses that ability to display the resources.
I also noticed it's not only the VMs running that can't be displayed using
the console ('no virtual machines present'). Even a display of SR
repositories fails with 'no storage repositories present'.
