Hi
I have a 2950 too, with 8Gb of memory.
I'm using FedoraCore5 64 bits, and you are right, with 64 bits OS, you don't
need a PAE-kernel.
I just download the sources of Xen, using mercurial and compile it.
(I have a lot of problems using precompiled packages, so don't loose your
time, compile your own xen-kernel)

Asunto: [Xen-users] VT 64bit kernel with >4Gb RAM
Hi there,
I have the lucky task to setup a Xen system.
my plateform is a dell 2950 with 16Gb of RAM.
I got as far as setting up debian sarge and xen following
http://www.debian-administration.org/articles/423
and overcoming some specific difficulties
(http://kmuto.jp/b.cgi/debian/d-i-2615.htm &
http://wiki.ncsa.uiuc.edu/wiki/Dell_PE1950_NIC_Firmware_Workaround)
But, my concern now, while I'm struglling to setup my 1rst VM, is that I
don't see all the RAM.
Still I 'm using both dual cores as cat /proc/cpuinfo lists 4 processors
>From my understanding, if I had a 64bit kernel I'd see them (pae beeing
only for 32bit systems, right ?)
And I'm guessing if I want to VMise 64bit OSes, I'll need it.
So :
Is there a debian prepackaged kernel that'd do the trick, or do I have
to compile my own ?
In the afirmative, what patch should I apply and where is that friendly
64bit option ?
Is there something else I'm missing ?
Thanks,
GdL.

PS : if I can't have it all by thursday, my boss'll end-up buying GSX
... =o(
BTW , is it conceivable to run ESX and/or GSX as a VMs on XEN ? (kindda
russian dolls concept)
