Dear James
I can confirm now the only remaining issue with the GPLPV drivers: the
windows virtual machines do not reboot, the domains must be destroyed and
restarted. The problem is that the memory does not get returned to the
machine after a domain is destroyed. That is a bug filed by Novell a couple
of days ago. The restart problem is on the drivers because the same machine
with Novell PV drivers restarts just fine. I can give you access to one of
my servers if you want to perform some tests.

Which version are you looking in? The very latest versions no longer use
/gplpv to activate the drivers, they only use /nogplpv to deactivate the
drivers. Booting in safe mode will also deactivate the drivers.

The parsing of the boot line is (I think) only done in xenpci.c now.
