A pathetically simple question about Xen
I'm probably missing something really obvious in my search for this information, but I really haven't found a clear answer so I decided to ask here, where there is lots of juicy knowledge.
Does Dom0 constitute a fully functional Linux OS?
What I'm getting at, really, is this; I have my day-to-day Linux installation that I wouldn't sacrifice if I can help it. I would like to also be able to run another system with virtualisation so that I have access to both at once, obviously. My concern is whether, if I install the Xen version of the kernel and other required software, my system will stay as usable as it is now.
Can I use my current installation as Dom0 without incurring any penalties? Or would I have to run a DomU for my daily tasks and would that be slowed by virtualisation?
