I find it a lot easier to clone the "Other Install Media" template and just set
the 3 fields to convert it into a PV template (clear HVM-boot-policy, set
PV-kernel to the MiniOS file in dom0, PV-args if you need). I think my old
blog entry on Ubuntu HVM->PV has more of the gory details, but most isnt
necessary for MiniOS: http://community.citrix.com/x/4YINAg

To access the raw serial console by text (the equivalent of 'xm create -c'),
you first need to disable the VNC proxy from spawning (set the VM
other-config:disable_pv_vnc field to something), start the VM paused, and then
connect to it directly using xenconsole from dom0, and then unpause the VM
I use this small script in dom0 to automate this for a given VM uuid:
http://github.com/avsm/mirage/blob/master/scripts/run_minios
Although to be honest, for MiniOS work, I just find it far more convenient to
just use the lower-level Python toolstack, and then switch to XCP for the
higher level management stuff.
