If the Xen option is not on the GRUB menu, review the steps for installation and verify

that the GRUB boot loader has been updated. If the installation has been done without

selecting the Xen pattern, run the YaST Software Management, select the lter Patterns

and choose Xen Virtual Machine Host Server for installation.

After booting the hypervisor, the Domain0 virtual machine starts and displays its

graphical desktop environment. If you did not install a graphical desktop, the command

line environment appears.

Before starting to install virtual guests, make sure that the system time is correct. To

do this, congure NTP (Network Time Protocol) on the controlling domain:

In YaST select Network Services > NTP Conguration.

Select the option to automatically start the NTP daemon during boot. Provide the IP

address of an existing NTP time server, then click Finish.

NOTE: Time Services on Virtual Guests

Hardware clocks commonly are not very precise. All modern operating systems

try to correct the system time compared to the hardware time by means of an

additional time source. To get the correct time on all VM Guest systems, also

activate the network time services on each respective guest or make sure that

the guest uses the system time of the host. For more about Independent

Wallclocks in SUSE Linux Enterprise Server see Section 6.3.4, “Virtual Machine

Clock Settings” (page 67).

For more information about managing virtual machines, see Chapter 4, Managing a

Virtualization Environment (page 27).
