32-bits Xen only support 16GB memory at most.
I think to support 256GB memory, you have to use a 64-bits Xen at least.

Fix me if I'm wrong.

Subject: [Xen-devel] Hang when starting a 256GB PV guest.

Hi all,

I was using xen 3.4.0 ,32bit dom0 to do some test on a 1TB memory
system.When tring to boot a 256GB PV guest(both EL4 and EL5),it just
hang after the domain builder completed it work.

Is it tested for 256GB PV guest? Anyone ever do this successfully? And
any suggestions?

Thanks,
xiaowei
