In our previous tutorial, we have installed and configured OpenVZ on CentOS. In this tutorial, we will see how to install OpenVZ in Ubuntu 14.04.
1. Add OpenVZ Repository
Switch to root user:
First, we will add OpenVZ Repository.
cat << EOF > /etc/apt/sources.list.d/openvz-rhel6.list deb http://download.openvz.org/debian wheezy main # deb http://download.openvz.org/debian wheezy-test main EOF
Import OpenVZ GPG key:
apt-key add archive.key
2. Install OpenVZ kernel
Update software sources using command:
sudo apt-get update
Now, install OpenVZ kernel:
apt-get install linux-image-openvz-amd64
Or, if you still have i686:
apt-get update && apt-get install linux-image-openvz-686
3. Setting up Kernel parameters
Make sure you have added the following kernel parameters before logging into vz kernel.
Add the following lines:
# On Hardware Node we generally need # packet forwarding enabled and proxy arp disabled net.ipv4.ip_forward = 1 net.ipv6.conf.default.forwarding = 1 net.ipv6.conf.all.forwarding = 1 net.ipv4.conf.default.proxy_arp = 0 # Enables source route verification net.ipv4.conf.all.rp_filter = 1 # Enables the magic-sysrq key kernel.sysrq = 1 # We do not want all our interfaces to send redirects net.ipv4.conf.default.send_redirects = 1 net.ipv4.conf.all.send_redirects = 0
5. Install OpenVz usage statistics tools
The following tools to be installed to gather the OpenVZ usage statistics. Here is the reason why you should install these tools.
apt-get install vzctl vzquota ploop vzstats
That’s it. We have successfully installed OpenVZ.
Now, it’s time to reboot and log in to OpenVZ kernel(it should be the default choice in the boot loader). In Ubuntu 14.04, it should be under Advanced options in the boot loader menu.
We’ll see how to create virtual machines using OpenVZ in our upcoming tutorials.
While creating VMs, make sure you have the same subnet on both physical and virtual machine. If you want to use different subnet, you have to edit /etc/vz/vz.conf file,
Find and uncomment the line:
And, change it to:
Ok, I have installed OpenVZ in Ubuntu, now what?
