Re: [Xen-users] Xen-Kernel detects just 3.2GB Ram on a 64Bit Debian

["Roman Konz" <drummermonkey@xxxxxxxxx>]

Hi Peter,

i have tried XEN 3.0.4 which is shipped with debian itself.
Then i've tried to install the official binary package of XEN 3.1,
and it gave the same error.
Compiling XEN 3.1&its shipped Kernel also don't work.

I'm not sure, but I think it must be an error in the XEN Kernel.
The same version (2.6.18) compiled without XEN support works fine with
8G of memory.

Now i have tried the evaluation of XEN Enterprise - same error.
A Hardware-Failure is not possible because i have tried it on 2 (same
Hardare) Computers.
Is it possible, that the XEN-Patch does not support our Hardware?

Thanks a lot

Greets,
Roman Konz
