Xen users - Feb 2008 - Problem with PAE-less processor in xen 3.1.0

Hello xen-users,

I have two days (or rather nights) ago start to play with xen. I have
quite old laptop without PAE support, so when I try to install xen
3.1.0 there was error saying, that I cannot run PAE-enabled kernel on
PAE-less processor. So I build and install PAE-disabled kernel (for
dom0), but I can''t find the way to turn off PAE i XEN micro-kernel. Is
there any manner to change XEN micro-kernel in 3.1.0 version to be
PAE-disabled ?

I get folowing messages, when booting xen kernel:

(XEN)  Xen kernel: 32-bit, PAE, lsb, paddr 0x100000 -> 0x664000
(XEN)  Dom0  kernel: 32-bit, lsb
(XEN) Mismatch between Xen and DOM0 kernel
(XEN)
(XEN) ****************************************
(XEN) Panic on CPU 0:
(XEN) Could not set up DOM0 guest OS
(XEN) ****************************************
(XEN)
(XEN) Reboot in five seconds...

In above, I made error, should be:

Xen kernel: 32-bit, PAE, lsb
Dom0 kernel: 32-bit, lsb, paddr 0xc0100000 -> 0xc042dd3c

Hi,

you need to use the same architecture for the hypervisor and dom0.
If your hypervisor is PAE, your dom0 also has to be PAE.

AFAIK PAE should be no problem on older hardware.

cheers

Stephan

Yes, this helped. I don''t know why I didn''t look at the
README... I
searched in Makefiles in xen subdirectory :(. Thank You.
