Fedora Core 7 (FC7) Xen/KVM Guide

Installing the Xen Software

When doing a fresh install of Fedora 7, Xen can be installed by selecting Virtualization in the Base Group in the installer.

For an existing Fedora 7 installation, the Xen kernel and tools can be installed by running the following command:

  • # yum groupinstall 'Virtualization'

This installs the required packages and their dependencies. 'kernel-xen' contains the Xen-enabled kernel for both the host and guest operating systems as well as the hypervisor. Also, the 'xen' package will be installed, which contains the user-space tools for interacting with the hypervisor.

Once this is done, there should be an entry in the file /boot/grub/grub.conf for booting the xen kernel. The xen kernel is not set as the default boot option.

To set GRUB to boot with kernel-xen by default, edit /boot/grub/grub.conf and set the default to the xen kernel: 2

This is an example /boot/grub/grub.conf configured to boot into the Xen hypervisor:

  • default=0
    title Fedora (2.6.20-2925.5.fc7xen)
            root (hd0,0)
            kernel /xen.gz-2.6.20-2925.5.fc7
            module /vmlinuz-2.6.20-2925.5.fc7xen ro root=/dev/VolRoot/LogVolRoot rhgb quiet
            module /initrd-2.6.20-2925.5.fc7xen.img
    title Fedora (2.6.20-1.3084.fc7)
            root (hd0,0)
            kernel /vmlinuz-2.6.20-1.3084.fc7 ro root=/dev/VolRoot/LogVolRoot rhgb quiet
            initrd /initrd-2.6.20-1.3084.fc7.img
