Install kernel from RPM on Ubuntu 10.04

You can use the latest RHEL6-based kernel builds on your Ubuntu 10.04 machine. Here's how.

Installation

1. Get the latest kernel and utils from Download/kernel/rhel6 and Download/utils. You need

• vzkernel
• vzkernel-devel
• vzctl
• vzctl-lib
• vzquota

vzkernel-devel is optional. Newer vzctl will also need ploop-packages!

2. Install fakeroot and alien.

apt-get install fakeroot alien

3. Convert all the RPMs to debs using alien.

fakeroot alien --to-deb --scripts --keep-version vz*.rpm
fakeroot alien --to-deb --scripts --keep-version ploop*.rpm

4. Install debs.

dpkg -i vz*.deb
dpkg -i ploop*.deb

5. Modify /boot/grub/menu.lst like this. This heavily depends on your enviornment. Please modify. See also “configuring the bootloader” of Quick installation.

initrd          /boot/initrd.img-2.6.32-38-server

6. Edit /etc/sysctl.conf. See “sysctl” of Quick installation.

7. Make OpenVZ boots automatically.

update-rc.d vz defaults
update-rc.d vzeventd defaults

8. If you plan to use LVM2, make sure the module dm-mod is loaded at startup:

echo "dm-mod" >> /etc/modules

9. Reboot.

reboot

10. Follow the Quick installation from “installing OS template caches”.

10b. rsyslog probably won't work (it depends on a debian-specific kernel-hack). See [1] on how to get it working again.
