LXC on Debian Wheezy

in virtualization, containers, lxc

LXC (LinuX Containers) offers a lot of the advantages of (para)virtualisation with the added benefits that it can run on any kind of hardware (it doesn’t need hardware support for virtualisation) with lower overhead than virtualisation. The virtual environments that LXC provides are comparable to a chroot but LXC adds control over the virtual environments resources like CPU-time and network-usage and offers more isolation. This also means it’s only possible to run the same “family” of guest operating systems as the host. I.e. it’s not possible to run Windows using LXC, but it is possible to run different Linux distributions like a Debian and Fedora guest on an Arch Linux host. Note that if you need a really secure environment LXC isn’t the right choice, stick with paravirtualisation like KVM or XEN instead.
