Re: [Xen-users] Xen 3.0 - dom0 with 32bit userland vs domU with 64bit userland?

The only caveat (that I know of) is that the dom0 Xen tools need to be 64 bit 
(because they talk to 64bit Xen, which has a different ABI).  This in turn 
means you'll need a 64-bit python install, etc etc.  A 64 bit dom0 userland 
might be easier from your PoV.

32 bit compatibility for normal userspace apps should work fine though, so 
running 32bit apps will usually be fine in either dom0 or domU.

Mark
