Chapter 8. Virtualization168You will then need to edit the /etc/grub.conf configuration file to boot the new xen kernel bydefault. To do this, select the lines in grub.conf that pertain to the xen kernel from the beginningof the title line to the end of the initrd line, copy the lines, delete them, and paste them sothey are the first kernel entry in grub.conf. Also ensure that the value of the default variable at thetop of grub.conf is set to a value of '0'.5. Reboot the system, boot it into the xen kernel. The system should not automatically boot into thexen kernel on reboot but if you would like to make sure it has for troubleshooting purposes, use thecommand uname -r to see if the running kernel is a xen kernel. If you do not see the xen string inthe name of the kernel, you have not booted into the correct kernel.NoteIf the system already has xen and kernel-xen installed you do not need to rebootafter installing rhn-virtualization-host.6. You will also need to install and run the osad package in order for your host system to beresponsive to commands sent from the Satellite, such as start, pause, resume, and shutdown. Toinstall:yum install -y osadafter installation, you should then start the osad process:/sbin/service osad restart7. Your host system should now be ready for RHN virtual guest provisioning.8.2. Setting Up Your Virtual SystemsIn order to work with virtual guest systems, you must first create a kickstart profile that will allow you toeasily provision virtual guests, then you must provision the guests.8.2.1. Create a Kickstart Profile for the Guest Systems1. Log on to the Satellite's web interface. Navigate to the Kickstart Overview screen by clicking onthe Manage Kickstarts link in the Tasks widget in Your RHN, or by clicking on Systems in the topnavigation bar Kickstart from the left navigation bar.2. On the Kickstart Overview page, click the Create a new Kickstart Profile link in the KickstartActions widget in the upper right corner.3. The next page displayed is Step 1 of the kickstart profile creation process:a. Enter a label for the profile that will allow you to distinguish it from the other profiles. A goodchoice would be guest-system.b. For the Base Channel field, select Red Hat Enterprise Linux $PRODUCT (v.5 for $ARCH)where $ARCH is the architecture of your host system's operating system and $PRODUCT iseither Server or Client.
