Re: [Xen-users] 32bit domU on 64 bit dom0

The 32-bit domU shouldn't need 3.1 patches to run on 64-bit Xen.  Any older 
domU kernel should work so long as it supports PAE.

Thread local storage also works exactly as it should on 32-bit guests on 
64-bit Xen, even with older setups that use negative segment references - so 
that's quite handy too.

Cheers,
Mark
