Fedora xen - Nov 2006 - xen fedora 6 on thinkpad t41

Hi,

i tried to run fedora 6 and xen on a thinkpad t41,
as already stated in http://fedoraproject.org/wiki/FedoraXenQuickstartFC6
this will not work on a t41 because it does not have a PAE enabled cpu.

My questions are:

1. Would i be able to run xen on a non-pae cpu when i compile xen myself or is
pae cpu a requirement for xen3.0.3

2. If a pae cpu is not requrired by xen 3.0.3, itself, why was the decision
taken to not support non-pae cpu under fedora 6 with xen.

Thanks

Frank

I read that the old FC5 0 and U kernels work. Haven''t tried.

   Obscure bug of 2004: BASH BUFFER OVERFLOW - if bash is being run by a
normal user and is setuid root, with the "vi" line edit mode selected,
and the character set is "big5," an off-by-one errors occurs during
wildcard (glob) expansion.

I ''m not qualified to comment on 1) as I haven''t tried, but...
Wrt. 2, I believe that the Fedora team decided to drop non-PAE support
because of the extra work required in maintaining two branches of
kernel patches (xen and xen0/xenU kernels). One argument I read, was
that since most of the latest generation CPUs are PAE capable there
wouldn''t be much harm done....
At least that how I understood it, after sifting through a bunch of
mailinglists, releasefiles and changelogs.

Btw. I found out about this only after I had upgraded my T42p to FC6. :-)
It kind of sucks that a 2 year old top-of-the-line laptop is now
"outdated"...

Cheers,
Kenneth
