Actually can get it working, but it involves a little more setup than
with paravirt.

In the Xen config file for the HVM guest add

   serial='pty'

In the grub.conf for the guest you need to have

   console=tty0  console=ttyS0,9600

And in the /etc/inittab for the guest you need to add

   s0:2345:respawn:/sbin/agetty -L 9600 ttyS0 vt100

That basically configures a virtual serial console in QEMU, tells the
kernel to send messages to it as well as the normal console, and finally
runs a login process on the serial console

IIRC that ought to be enough to make 'xm console' work kfor HVM

Dan.
