Thread-topic: PoD in other (not GPLPV) drivers
I'm looking at PoD support in GPLPV. There was a bug preventing the
initial balloon down of DomU which I've now fixed, but it's still a bit
of a race with Windows to try and balloon down the pages before Windows
tries to use them. Under Windows 2008 x32, memory=512 + maxmem=1024 is
enough to crash the system just after my DriverEntry is called.

Do other Windows PV drivers support PoD? Under what scenarios? I'm
trying to figure out how achievable this is.

Thanks

James
