I haven't had any head way in this. The Dom0 boot messages do hint that
hvc0 console is enabled. The file system seemed to be missing an hvc0
device, and I later created one using mkdev (229,0), but with no avail.

I'm trying to understand what sequence of events are expected to happen
to debug this: Is upstart expected to call agetty with hvc0? Are there
any options to enable logs from upstart? Are there any extra options to
be enabled in the Dom0 kernel other than Xen support?
