Xen devel - Dec 2006 - demo cd 3.0.3 on non-pae machine

Hi all,

Would it be possible to include support for a non-pae capable machines
on the demo cd. The 3.0 version worked but the 3.0.3 version fails with

Cannot execute PAE-enabled kernel on a PAE-less CPU!

(Please CC me since I am not subscribed to the list)

Thanks,

What CPU do you have that doesn''t support PAE? AMD has had PAE since K6
or K5 days, Intel had it before then...

Whilst I understand that someone may wish to not build Xen for
themselves, I also think that the number of actual potential customers
of Xen that has processors that doesn''t support PAE are fairly
limited...

This is the output of /proc/cpuinfo (while running Ubuntu edgy):

The machine is a Dell Latitude D505.

This machine is about 2 years old, so still appropriate to test the Xen
Demo CD, no ? :) I assume adding non-pae kernels just implies changing
the build scripts or doesn''t new Xen support non-pae processors
anymore?

How about "What OS do you have that does not support PAE?". A
different question, with a different answer. And, I have such an OS,
and, it would not boot under the Xen RPMs.

I am finding, however, that the best way to run Xen is to skip the
tarballs, RPMs, etc. and just hg the source tree and build from
scratch. That solved all my FC4 problems.

But I don''t think the attitude of "we know best what you
want" is
really very helpful, especially since it is not correct.
