Tory, first of all that's simply great! I've just started to work on Xen
and SI integration, so I'm really interested in this topic!!!
Question: are you running Xen in HVM mode to image the VM clients? And
after the imaging you can choose to switch to paravirtualized mode or
simply reboot and continue to use HVM, right?

This is true if you used --autodetect-disks in si_getimage (or
si_mkautoinstallscript), but it should work if you don't use this
option. Just replace all the /dev/sda occurrences to /dev/xdva in
/var/lib/systemimager/images/YOURIMAGE/etc/systemimager/autoinstallscript.conf
and re-create the .master script by si_mkautoinstallscript.
Anyway, the --autodetect-disks issue can be easily fixed as you
suggested adding xvd to the DISKORDER list.

Yes, as expected, SC doesn't know what /dev/xdv* are, I suppose that's
very similar to the SI issue above. I'll look at it.

Well, I've never understood how the donation system works on SF.net...
if you wanna try :-) Anyway, as I said in a previous mail, we would
really need a x86_64 server to build deb and RPM packages for this
architecture. Do you have a x86_64 machine online? a non-privileged
account would be enough to build SI packages, or better, you could
contribute building x86_64 packages for us if you're interested.
BTW have you registered your SI installations on the cluster map? ;-)
Thanks,
-Andrea
