The referenced link (https://wiki.xen.org/wiki/Xen_Linux_PV_on_HVM_drivers)
looks to be about adding to the older configuration style file. I do not
see the proper incantation for the " xen_platform_pci=1" in the domain xml
file syntax. I'm not even sure if I attempted it correctly. Is there a
portion of that page that pertains explicitly to booting? I think I missed
something.

Thanks
