Hello, I installed Xen on a Debian Etch following this tutorial : http://www.howtoforge.com/debian_etch_xen_3.1_p2 The problem is that it only recognizes 3.5GB of RAM although I have 8GB ! I then found this tutorial to help fix this : http://www.howtoforge.com/make-your-xen-pae-kernel-work-with-more-than-4gb-ram-debian-etch-grub Didn''t change anything really... Does anyone have an idea, how I can remove this limit ?

I think so.I think you now have to have PAE for 32bit xen regardless of how much memory you have, but as I said it''s been a fair since I used 32bit with xen. _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
I think the problem is that the tutorial does not use the PAE version of 32-bit Xen. I will be trying that :) Thank you for your answers Antoine On Fri, Sep 12, 2008 at 12:04 AM, Andy Burns <xen.lists@burns.me.uk> wrote:> 2008/9/11 Grant McWilliams <grantmasterflash@gmail.com>: > > > Don''t you have to have the 32 bit PAE kernel or 64 bit in order to > address > > more than 3.5 GB?

I confirm ! If you follow this tutorial, you need to download http://bits.xensource.com/oss-xen/release/3.1.0/bin.tgz/xen-3.1.0-install-x86_32p.tgz Notice the extra "p" :P Antoine who just spent a day pulling his hair out for a missing "p" On Fri, Sep 12, 2008 at 9:45 AM, Antoine Benkemoun <antoine.benkemoun@utt.fr> wrote:> I think the problem is that the tutorial does not use the PAE version of > 32-bit Xen.

Just in case , i would try make sure you are running 64-bit system:-
# uname -a
3.5 GB RAM is a limitation for any 32-bit system (Windows,Linux)

Hello,
I installed Xen on a Debian Etch following this tutorial :

The problem is that it only recognizes 3.5GB of RAM although I have 8GB ! I then
found this tutorial to help fix this :

Didn''t change anything really...
Does anyone have an idea, how I can remove this limit ?
Thank you in advance,

Hi> Just in case , i would try make sure you are running 64-bit system:- > # uname -a > 3.5 GB RAM is a limitation for any 32-bit system (Windows,Linux)No. 3.5GB is the limit for pure 32bit, but with PAE you can allocate up tp 64G (AFAIK). Only single processes are limited to ~3GB. This counts for Windows and Linux.
