Xen connect to dom0 with vnc?

Solution 1:

So, I've found the answer, as a result of another answer that was totally condescending and really upset me (and was deleted), but forced me to dig and dig to figure out how to do this. The answer lies within x11vnc, which was apparently created partly for this purpose. Luckily, Xen actually installs x11vnc for me, so I don't even have to install it. Just run:

sudo x11vnc -rawfb console

and blammo, vnc to the console. Like a KVM, but requires network. There are a million options for x11vnc, and I haven't explored them all yet, but this is perfect and exactly what I need. To run it in the background, add a bg flag:

sudo x11vnc -bg -rawfb console

Solution 2:

What about the 'screen' command's -rx option - which allows you to connect to an already active screen session of a user on the local machine, and see and interact with everything they see.

It could get a bit hairy trying to keep your wits with several hundred screen sessions - but it hardly seems worse than several hundred VNC session...
