If you look at xm info you should see the list of supported architectures on a line with the label "xen_caps." My 64-bit XEN boxes require that domUs use a 32-bit PAE kernel.

Hi,
I tried to start a 32Bit PVM system on a 64Bit dom0, and got the following
error:
Using config file "./VM1".
Error: (2, 'Invalid kernel', 'xc_dom_compat_check: guest type xen-3.0-x86_32
not supported by xen kernel, sorry\n')
and it just did not started. Is ist just because of the different 32/64Bit
of domU and dom0? The xen in the dom0 is configured to be backward
compatible. The dom0 is a xen 3.1.0, the domU is a xen 3.0.3.
When this is just not working, then I have to run the dom0 in 32Bit. Do I
can then assign 4GB RAM to each domU, or will the dom0 be unable to handle
that amount of memory? I assume I need a PAE enabled Xen kernel for the
dom0? But will I need such a kernel then for the domU's too?
kind regards
Sebastian
Sorry if this mail hits the M/L twice, I sent the original yesterday
afternoon, and still nothing on the list, therefore resending it now.
