Xen users - Jun 2008 - Xen HV 64bit?

I need to support 32GB of ram, the 32bit HV wont do this i guess.  Can i run 
a 64bit HV with a 32bit Dom0 and a 32bit DomU?

Also, i tried building a 64bit HV on a 32bit dom0 but it failed, is it not 
possible to build a 64bit HV on a 32bit dom0?

AFAIK, the dom0 has to be 64bit, but domUs can be 32bit as long as PAE
is supported.

It isn''t possible to build a 64bit anything on a 32bit toolchain.

Yes, Oracle VM does this.  Your mileage will vary according to which 
version of Xen you are using.

In this particular case you''re cross-compiling.   Basically you want 
"gcc -m64 helloworld.c" to produce a 64-bit binary and once
you''ve got
that, the rest will be a breeze :-)  You''ll probably want a 64 bit 
machine to test that on though so you might as well do the build on that.
