HP Insight Control for Linux 6.2 User Guide

Check that the configured MAC address matches the DNS/DHCP entry. The virt-manager
command might display MAC addresses beginning with 00:16:3e, but configure the NIC to start
with 52:54:00 instead. You can adjust the MAC address by running these commands on the KVM
virtual host:
1. Use the following command to shut down the virtual guest:
# virsh shutdown virtual_guest_name
Watch the console to determine that the virtual guest is completely shut down.
2. Edit the MAC address with the virsh edit command:
# virsh edit virtual_guest_name
Save your changes and exit the editor.
3. Restart the virtual guest:
# virsh start virtual_guest_name
11.3.3 Guidelines for configuring a Xen virtual guest
This section describes one possible method to create and configure a Xen virtual guest. There
are many other ways to accomplish the same result.
You will need the virt-manager utility and an X window session to create a virtual guest. Be
sure to consult the documentation for the virt-manager utility
For information on licensing virtual guests, see Section 3.3 (page 30).
IMPORTANT: The RHEL Kickstart and SLES AutoYaST configuration template files for virtual
guests are delivered with a hard-coded root password, which poses a security issue if used
without modification.
For secure installations, HP recommends that you install the virtual guest operating systems in
a manner that keeps the root password secure, such as an interactive installation, or use a Kickstart
or AutoYaST file that is properly protected on the local host.
Secure installations should not store the root password on the CMS.
Use the following guidelines for configuring a Xen virtual guest:
• Verify that the Kickstart or AutoYaST file for the virtual guest resides in the
/opt/repository/instconfig/osver-virt-guest-xen directory on the CMS, where
osver indicates the operating system version, for example, rh055.
The format of the Kickstart or AutoYaST file name is osver-virt-guest-xen.cfg.
• If you need to customize the Kickstart or AutoYaST file, do so before proceeding.
• Open an xterm window or a remote desktop connection to the virtual host.
• Run the virt-manager utility on the virtual host to create and name a new machine.
TIP: Consider matching the machine name to the host name in a virtual machine map. See
Section 23.10 (page 211).
• Select the Paravirtualized option for the virtualization method.
• The installation media URL (also called the Network URL) for the operating system must
link to the Insight Control for Linux Repository:
http://CMS:port/instconfig/os/os_specifier
Where:
CMS Is the fully-qualified IP address of the CMS
port Is the port used
