37.3. Configuring a Xen Guest Domain

SUSE LINUX Documentation Chapter 37. Virtualization with Xen / 37.3. Configuring a Xen Guest Domain

The documentation about how to configure a guest domain is not very exhaustive. The most information about how to configure such a domain can be found in the example configuration file /etc/xen/config. The needed options are explained together with a default value or at least an example configuration. For the installation described in Section 37.2.1, “Using YaST to Install a Guest Domain”, create a file /etc/xen/guest1 with the following content:

kernel = "/boot/vmlinuz-xen"   
ramdisk = "/boot/initrd-xen"   
memory = 128                   
name = "guest1"                
nics = "1"                     
vif = [ 'mac=aa:cc:00:00:00:ab, bridge=xen-br0' ] 
disk = [ 'file:/var/tmp/guest1,hda1,w' ] 
root = "/dev/hda1 ro"          
extra = "3"

	Enter the path to the Xen kernel in domain-0. This kernel will run in the guest system later.
	Select the appropriate initial RAM disk that contains the device drivers for the Xen kernel. Without this, the kernel typically panics because it is unable to mount its root file system.
	Define how much memory the guest domain should be given. This fails if the system does not have enough memory available for its guests.
	The name for this guest.
	The number of virtual network interfaces for the guest domain.
	The configuration of the virtual network interface, including its MAC address and the bridge to which it is connected.
	Set the available virtual block devices for the Xen guest. To use real block devices, create entries like `['phy:sdb1,hda1,w', 'phy:system/swap1,hda2,w']`.
	Sets the root device for the kernel. This must be the virtual device as seen by the guest.
	Add extra kernel parameters here. The example `3` means that the guest is started in runlevel 3.
