[Xen-devel] Compaq Proliant 2500 Dom0

[David Morgado <dcrmorgado@xxxxxxxxx>]

Hi,
I'm trying to boot xen dom0 on a Compaq Proliant 2500 but so far I
have been unsuccessful,  I get (XEN) Not enough memory to stash the
DOM0 kernel image.

On a normal linux 2.6 kernel to boot I have pass "memmap=exactmap
memmap=640K@0 memmap=319M@1M" to the kernel at boot otherwise it hangs
because of the way Compaq Bios reports the system memory.

I've tryed to use this same options to the xen kernel but to no
effect, serial console capture fallows.

Even with the Xen 3.0.3 Demo CD, I select Debian-based Dom0 in text
mode (from testing), I get the same results no mater what options I
pass to the kernel.

It seams that the kernel is not detecting all the memory available.
I've been searching the archives and on google and came up with
nothing, did I miss something?  Any help would be appreciated.

Thanks
David
