Nah, RHEL 5.1+ supports 32-bit domU (PAE and non PAE) on 64-bit dom0.
Actually RHEL Xen is 3.1 with the brain damaged 3.0 userland utilities.

I've run into an interesting problem, which trying to install a 64bit guest:
libvir: Xen Daemon error : POST operation failed: (xend.err 'Error creating domain: I need 524288 KiB, but dom0_min_mem is 262144 and shrinking to 262144 KiB would leave only 461040 KiB free.')

Even though Linux reports only 713MB RAM, the machine has 2GB RAM. How / where do I fix this?
I also saw this:

xen top shows the full RAM, but the system itself doesn't?
