Linux virtualization alternatives

2016-12-07 00:24:24

This comparison table is dedicated to compare OS virtualization engine for Linux.

These virtualization software works using a modified linux kernel. For this reason they run only on linux host and can only run linux guests with the same kernel. The advantages of these virtualization software is the performance which is assimilated to native. Also the RAM memory management is more flexible, since you might not have to dedicate an amount of RAM to a virtual server, so that if the virtual server does not use the memory others can use it.

Feel free to correct any mistakes, add relevant criteria or add another virtualization engine.

You might also be interested by the following comparison:


live migration: is the ability to move your virtual server on a different physical machine with a very small downtime, without having to reboot the virtual server.

snapshot support: is the ability to create a backup / copy of your current virtual machine.

libvirt support: libvirt is a toolkit (library / API) to control virtualization process so that you can create and control virtualized systems in a standard way. One API to control OpenVZ, lxc or other virtual machines like KVM/QEMU, Xen...
