Create a new fully virtual machine or start an existing fully virtual machine. Use YaST+Virtualization+Virtual Machine.

Get the latest updates for the operating system from your update channel.

Verify that the Xen drivers are installed.

1. Launch YaST by entering yast2 at a terminal.

2. Select Software+Software Management.

3. Search for xen-kmp and make sure that the appropriate drivers are installed for your system.

   If they are not selected, select them and click Accept to complete the installation.

In the VM Guest, edit the file /boot/grub/menu.lst. At the kernel line, append a parameter hdx=noprobe where hdx is the drive designation specified in the virtual machine configuration file. For example, the disk specification in your configuration file may look as follows:

disk=['file:/var/lib/xen/images/vm1/disk0,ioemu:hda,w', \
 'file:/var/lib/xen/images/vm1/disk1,ioemu:hdb,w' ]

In this example, the virtual machine configuration file specifies two virtual disks hda and hdb. If you want both disks to use the Xen drivers, add the parameters hda=noprobe and hdb=noprobe to your kernel command line as follows:

kernel vmlinuz-kernel_ver <other_options> hda=noprobe hdb=noprobe

Now, the devices /dev/hda and /dev/hdb are disabled, and the machine must be prepared to use the paravirtualized disk drivers. At the kernel line, change the root device to the paravirtualized disk device. For example, if the kernel line contains root=/dev/disk/by-id/xxx, change this entry to root=/dev/hdaX, where hdaX is the disk and partition of your root partition. For example, this will look like root=/dev/hda2.

Shutdown your VM Guest. The Xen paravirtualized disk driver will be used the next time you reboot this VM Guest.

If your VM Guest is running, first shut it down.

On the VM Host Server, open a terminal and enter xm delete vm_name to delete the virtual machine’s reference in the Xen store so it is no longer managed.

Enter xm list to see the name of the virtual machine (vm_name).

Open the virtual machine configuration file located on virtualization host server (/etc/xen/vm/vm_cfgfile, where vm_cfgfile is usually the same as the name of the virtual machine).

Remove all parameters from the vif= line except the mac=mac_address parameter. Make sure to leave the single quotes.

For example, change the line

vif=[ 'mac=00:16:3e:55:24:21,model=pcnet,type=ioemu', ]

to

vif=[ 'mac=00:16:3e:55:24:21,type=netfront', ]

At the terminal, enter xm new vm_cfgfile to reference the virtual machine in the Xen store so it is managed again.

Restart the virtual machine by using YaST+Virtualization+Virtual Machine Manager.

You can also restart the virtual machine by using xm start vm_cfgfile, but make sure to connect to it with a viewer.

The first time the virtual machine boots, you might see a message indicating that new hardware was found. This message can be safely canceled.

Run YaST.

1. Make sure you are logged in as root.

2. Open a terminal.

3. Enter YaST2.

In YaST, click Network Devices > Network Card.

Click Change, then select and delete each network card that is already configured.

Click Add, then change the ethx parameter to a network card number identified above. Repeat the process to add all virtual network cards.
