There is only

xen_caps : xen-3.0-x86_64 hvm-3.0-x86_32 hvm-3.0-x86_32p hvm-3.0-x86_64

but no "xen-3.0-x86_32p".

How can i change it? Another Dom0-kernel?

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. -Nick

Hello,

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?
