Thread-topic: [Xen-devel] Cannot access dom0 console

This does not affect the physical method of talking to the console at all.
It's just a change of name of the virtual console device. If you tell Xen to
attach its console to the serial line (console=com1), then dom0 virtual
console will also be on the serial line, just as before.
