xen3.4.0_another_install

1. First we need to add the YUM repository holding the updated Xen. Only use ONE of the following files depending on your CPU architecture!

 

Create the following file with a text editor and save it as /etc/yum.repos.d/gitco.repo

# Name: RPM Repository for Red Hat Enterprise 5 - gitco
[gitco]
name = Red Hat Enterprise $releasever - gitco
baseurl = http://www.gitco.de/linux/i386/centos/5/rpms_testing/
enabled = 1
protect = 0
gpgcheck = 0

 

2. Uninstall old Virtualization files

yum groupremove Virtualization

3. Install the relevant packages using YUM

yum groupinstall -y Virtualization

 

Yum will probably want to upgrade some other files along with the ones we've chosen.

Warning! If you get an error message from grubby this is bad!

Installing: kernel-xen                   ####################### [ 9/13]
grubby fatal error: unable to find a suitable template

This means that your grub.conf file couldn't be written to for whaterver reason. I'm not sure yet why this is happening but it basically means the grub.conf will be pointing to your old xen-kernel instead of your new one so you won't be able to successfully reboot. If you get this message you need to edit your /boot/grub/grub.conf file and make the kernel lines match the kernel you installed. To get your installed xen-kernel version check it with rpm.

[ root@vs / ] rpm -q kernel-xen

kernel-xen-2.6.18-92.1.6.el5

Now edit your /boot/grub/grub.conf to match

# grub.conf generated by anaconda
#
# Note that you do not have to rerun grub after making changes to this file
# NOTICE:  You have a /boot partition.  This means that
#          all kernel and initrd paths are relative to /boot/, eg.
#          root (hd0,0)
#          kernel /vmlinuz-version ro root=/dev/vgsys/lvroot
#          initrd /initrd-version.img
#boot=/dev/sda

4. Reboot - no really I mean it.

5. Try it out by using the xm dmesg command

[ root@vs ~ ] xm dmesg
