What kernel would I use if I wanted to use Xen on a server with more
then 4GB of ram and 2 processors?


Can the Xen kernel handle this?

Yes, it can.

Prior to 64-bit release of Xen hypervisor (that is, before the summer of
2007), the 32bit-PAE version of Xen allowed the use of up to 16GB of memory.

You can leverage up to 128GB of memory with a current 64-bit Xen modified
GNU/Linux kernel.

Hope the info is useful.

Thanks for the response

Just to be sure the RHEL Xen kernel (ex: 2.6.18-92.1.6.el5xen #1 SMP Fri
Jun 20 03:05:59 EDT 2008 i686 i686 i386 GNU/Linux) can handle over *4GB
of RAM *


*AND*

*over 2 processors?*
