If you are using the Virtual Machine Manager, you may also reconfigure the guests by
modifying the respective .sxp configuration. For more about this configuration option,
see also Section 4.3, "Configuring a Virtual Machine by Modifying its xend Settings"
(page 30).
2.5 Starting the Virtual Machine Host
If virtualization software is correctly installed, the computer boots to display the GRUB
boot loader with a Xen option on the menu. Select this option to start the virtual machine
host.
NOTE: Xen and Kdump
In Xen, the hypervisor manages the memory resource. If you need to reserve
system memory for a recovery kernel in Domain0, this memory has to be re-
served by the hypervisor. Thus, it is necessary to add the parameter
crashkernel=size@offset to the kernel line instead of using the line
with the other boot options. For more about Kdump, see also

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 filter 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, configure NTP (Network Time Protocol) on the controlling domain:
1 In YaST select Network Services > NTP Configuration.
2 Select the option to automatically start the NTP daemon during boot. Provide
the IP address of an existing NTP time server, then click Finish.
