How to Install OpenVZ on OpenBSD

OpenVZ is an open-source virtualization software that allows for multiple operating systems to run on a single physical machine. This tutorial will guide you through the process of installing OpenVZ on OpenBSD.

Prerequisites

  • OpenBSD machine
  • Root access to the machine
  • Internet connection

Step 1: Install Required Packages

Before installing OpenVZ, we need to install some required packages. Open up a terminal and run the following command:

# pkg_add curl wget gcc unzip

This will install curl, wget, gcc, and unzip packages, which will be used later in the installation process.

Step 2: Download and Install OpenVZ

OpenVZ doesn't have official support for OpenBSD, so we need to download and install the OpenVZ package manually. Follow these steps to do so:

  1. Open up a terminal and navigate to the desired installation directory.

  2. Download the OpenVZ package from the official website: http://openvz.org/download/kernel/

  3. Extract the contents of the downloaded package:

    # unzip file_name.zip

  4. Navigate to the extracted directory and run the following command to compile and install the OpenVZ kernel:

    # make kernel

    This will take some time to complete.

  5. Install the kernel using the following command:

    # make install-kernel

  6. You will also need to update the bootloader configuration file. Open the bootloader configuration file using a text editor:

    # vi /boot.cfg

  7. Add the following lines to the end of the file:

    1) OpenVZ-$(uname -r)
set kernel=OpenVZ-$(uname -r)
set ramdisk=rd.gz
boot

  8. Save and quit the text editor.

  9. Reboot the system to load the new kernel.

Step 3: Verify OpenVZ Installation

After the system has rebooted, we need to verify if OpenVZ has been installed correctly. Open up a terminal and run the following command:

# vzlist

If OpenVZ has been installed correctly, you should see an output similar to the following:

CTID NPROC STATUS IP_ADDR HOSTNAME

Conclusion

You have successfully installed OpenVZ on OpenBSD. You can now start using OpenVZ to create virtual machines on your OpenBSD machine.
