You might do a "xm info" to see what types of domUs are supported under the version of Xen you're running, which is displayed on the xen_caps line.  Mine looks like this:
xen_caps               : xen-3.0-x86_64 xen-3.0-x86_32p hvm-3.0-x86_32 hvm-3.0-x86_32p hvm-3.0-x86_64
What's important to note here is that the Xen version I'm running only supports 32-bit PAE kernels for PV domUs (for HVMs it supports non-PAE, but not for paravirtualized kernels).  Check yours and see which types of kernels are supported - you may need to use a PAE kernel, instead.

i run Debian Etch amd64 on my dom0,
if i try to create a domU with a 32Bit Kernel, i get:

Using config file "123.conf".
Error: (22, 'Invalid argument')         

If i try a 64Bit guest kernel, it works fine.

Is there a way to run a 32-Bit domU on a 64bit based dom0 os?
