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

Installation

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

  • vzkernel
  • vzkernel-devel

vzkernel-devel is optional.

For newer kernels with ploop-support you will not be able to use the vzctl package that comes with Ubuntu 10.04. So download the following rpm-packages from openvz.org as well

  • ploop
  • ploop-lib
  • vzctl-core
  • vzctl
  • vzquota


2. Install fakeroot and alien. 

apt-get install fakeroot alien

3. Convert all the RPMs to debs using alien and install the converted kernel 

fakeroot alien --to-deb --scripts --keep-version *.rpm
dpkg -i vzkernel*deb

4a. Install vz utils (only if you did not download vzctl and vzquota from openvz.org) 

apt-get install vzctl vzquota

OR

4b. Download and install libcgroup1 from the Ubuntu 12.04 repository for your architecture if you plan of using current versions of vzctl 

wget http://mirror.pnl.gov/ubuntu//pool/universe/libc/libcgroup/libcgroup1_0.37.1-1ubuntu10_i386.deb 
wget http://mirror.pnl.gov/ubuntu//pool/universe/libc/libcgroup/libcgroup1_0.37.1-1ubuntu10_amd64.deb

dpkg -i libcgroup1*deb
dpkg -i ploop*deb vzquota*deb vzctl*deb

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

default         0
timeout         3

title           Ubuntu 10.04.3 LTS with OpenVZ, kernel 2.6.32-042stab044.17
root            (hd0,0)
kernel          /boot/vmlinuz-2.6.32-042stab044.17 root=/dev/sda1 ro console=tty0
initrd          /boot/initrd.img-2.6.32-042stab044.17

title           Ubuntu 10.04.3 LTS, kernel 2.6.32-38-server
root            (hd0,0)
kernel          /boot/vmlinuz-2.6.32-38-server root=/dev/sda1 ro console=tty0
initrd          /boot/initrd.img-2.6.32-38-server

6b. If using grub2, please modify /etc/default/grub and change GRUB_DEFAULT to whatever your new grub entry is named (check your menuentrys in /boot/grub/grub.cfg) 

"GRUB_DEFAULT="Ubuntu, mit Linux 2.6.32-042stab061.2"

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

8. Make OpenVZ boots automatically. 

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

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

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

10. Reboot. 

reboot

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

11b. rsyslog probably won't work (it depends on a debian-specific kernel-hack). See [1] on how to get it working again.

12. See also Common Networking HOWTOs.
