Giving control back to dom0 is not possible...Once you stop the domU (safe shutdown), you need to restart the dom0

Another question, this time it should be rather easy.
If I have 2 VGAs, and I manage to pass one to the DomU (Secondary 
adapter passthrough should be doable for Xen >= 4.0 right? but that's
 not important) can I still use a VNC connection to the DomU? I hope the
 answer is yes, but I prefere asking since something strange might get in the way and cause problems perhaps.
