Yes, thanks.  Uncommenting "serial_device = hvc0" in
/etc/xen-tools/xen-tools.conf was enough to get me to a login prompt with
"xm console <dom-id>.  But it still didn't allow an ssh login:

----------- begin transcript -------------
~# ssh 192.168.153.110
ssh: connect to host 192.168.153.110 port 22: Connection refused
------------ end transcript --------------

I tried another run of xen-create-image with the udev role appended.  That
didn't fix the ssh problem.  It appears that ssh is not installed:

----------- begin transcript -------------
~# xm console 1
.
.
.
Starting periodic command scheduler: crond.

Maybe I should file a bug against xen-tools given that man xen-create-image
states that the new domU will be created with a working Openssh setup ?

Thanks for helping,
