Installing openVZ on CentOS
Installation steps have been learned from http://wiki.openvz.org/Quick_installation
Following steps can be used to install openVZ on CentOS machine:
- Download openvz.repo file from http://download.openvz.org/openvz.repo
- mv openvz.repo /etc/yum.repos.d
- yum install vzkernel.x86_64 ovzkernel.x86_64 vzctl.x86_64 vzquota.x86_64
- Disable SELinux
- Enable forwarding of packets in iptables firewall
- Create a folder where you want to store openVZ related stuff. Create symbolic link of choosen folder as /vz.
- Download templates from http://download.openvz.org/template/precreated/ to '/vz/template/cache. #:For centos template we need to rename it to -default template using 'mv centos-5-x86_64.tar.gz centos-5-x86-64-default.tar.gz' as for some reason vzctl tries to append `-default' when we create containers using centos template.
- Optionally Edit file '/etc/grub.conf' and change title of kernel with word stab in it to openVZ. Remove all parameters passed to this kernel except "ro root=...". The setup works better without doing this as it does not leads to printing of too many messages during boot.
- Reboot into openVZ kernel
Note that container filesystems get stored in /vz/private/<container_id>
