If you notice supported guest types is xen-3.0-x86_32p  thats PAE
enabled guest.

Now, I want to run a 32bit freebsd domU which doesnt have PAE support.
When I try booting this domU i get compatibility error as it is not
PAE enabled.

How do I ensure that domO supports xen-3.0-x86_32 guest along with (
or without xen-3.0-x86_32p )

Hi,

You need check
xen/arch/x86/setup.c(arch_get_xen_caps())
Anyway You need off CONFIG_X86_PAE.


Thanks
