2.3.1 Setting a Maximum Amount of

Memory

Determine the amount of memory to set for domain 0.

At Domain0, type xm list to view the currently allocated memory.

Run YaST > Boot Loader.

Select the Xen section.

In Additional Xen Hypervisor Parameters, add dom0_mem= mem_amount where

mem_amount is the maximum amount of memory to allocate to Domain0. Add

K, M, or G, to specify the size, for example, dom0_mem=768M.

Restart the computer to apply the changes.

2.3.2 Setting a Minimum Amount of Memory

To set a minimum amount of memory for Domain0, edit the dom0-min-mem param-

eter in the /etc/xen/xend-config.sxp le and restart xend. For more informa-

tion, see Section 4.2, “Controlling the Host by Modifying xend Settings” (page 29).

2.4 Networks Card in Fully Virtualized

Guests

In a fully virtualized guest, the default network card is an emulated Realtek network

card. However, it also possible to use the split network driver to run the communication

between Domain0 and a VM Guest. By default, both interfaces are presented to the

VM Guest, because the drivers of some operating systems require both to be present.

When using SUSE Linux Enterprise, both network cards are available for the VM Guest.

The MAC addresses of both cards are identical in this case, which leads to problems

when running the network. The following network options are available:
