| Linux Containers, or LXC, is a Linux feature that allows Linux to run one or more isolated virtual systems (with their own network interfaces, process namespace, user namespace, and power state) using a single Linux kernel on a single server. To learn more take a look at the [[LXC]] article.

| Creating containers is quite easy using lxc-templates. They are located in the /usr/share/lxc/templates directory. You can find there many distributions like archlinux, centos, debian, fedora, opensuse, ubuntu, gentoo and some more. There is also an inofficial funtoo template that can be found at https://github.com/golodhrim/lxc-funtoo/blob/master/lxc-funtoo. The script creates funtoo container, however I was not able to use it with lxc-create script from the lxc utils.

| So how do you create other containers? I am going to use a debian container for this purpose. You will have to emerge debootstrap.

| After this you can create your debian container using:

| | |
| <console>
| |
| ###i## lxc-create -n vm1 -t debian
