I've read in many posts, that XEN limits the 32 bit PAE kernel to 16 GB
RAM, but I don't find were to enable more. Starting linux without XEN
shows the whole memory. Is there still no solution?

I don't have the possibility to upgrade the server to 64 bit.


You can run 64bit hypervisor (xen.gz) with a 32bit PAE dom0 Linux kernel.
Maybe that's an option for you..

if it works, why not! But what are the issues about this solution?


That allows you to use all the available memory for VMs, and dedicate
some memory (say, 1GB) for a 32bit dom0.

sounds really good, I'll try this asap.

Thank you
Daniel
