Edit the GRUB boot loader settings by running YaST > System > Boot Loader or

editing the le at /boot/grub/menu.lst.

Change Hypervisor to /boot/xen.gz.

The xen.gz hypervisor is the 64-bit hypervisor.

Reboot the computer.

During the boot process, select the Xen option from the GRUB boot loader.

Verify that the computer is running the 32-bit Domain 0 by entering:

uname -m

It should report a 32-bit machine name, such as i686.

Verify that the computer is running the 64-bit hypervisor by entering:

xm info | grep xen_caps

It should report a 64-bit Xen hypervisor, such as xen-3.0-x86_64.

2.3 Managing Domain 0 Memory

When the host is set up, a percentage of system memory is reserved for the hypervisor,

and all remaining memory is automatically allocated to Domain0.

A better solution is to set a minimum and maximum amount of memory for domain 0,

so the memory can be allocated appropriately to the hypervisor. An appropriate minimum

amount would at least be 512 MB.

On 64bit machine with more than 480 GB RAM Setting a maximum amount needs to

be set, otherwise the machine may refuse to boot. Set the value at or below the boundary

of 480 GB—the difference is reserved for the hypervisor (to be used for guest VMs).
