August 30, 2019

by ServerOk with No Comment Virtualization

LXD is tool to manage LXC (Linux Containers). lxd allow you to create and manage light weight linux containers, it is like docker, but more like an actual virtual machine. LXD is more user friendly than using LXC directly, have more features like clustering of servers.

On Ubuntu/Debian, run

apt install -y lxd lxd-client

1	apt install -y lxd lxd-client

Before you start using lxd, run

lxd init

lxd init

Just press enter for all questions. Defaults should work. lxd is demaon, only used one time during “lxd init”. After this, you will be using lxc command for everything.

To create a container, run

lxc launch ubuntu:18.04 vm-1

1	lxc launch ubuntu:18.04 vm-1

To list all containers, run

lxc ls

lxc ls

lxc list containers

To stop a VM, run

lxc stop VM-NAME

1	lxc stop VM-NAME

To start VM,

lxc start VM-NAME

1	lxc start VM-NAME

LXD container snapshot and restore

lxc is Linux Container, allow you to run light weight virtual servers on your computer.

It is better use LXD instead of LXC as LXD provide much easier to use interface to LXC.

To install lxc, run

apt install -y lxc

1	apt install -y lxc

To create a VM, use

lxc-create -t download -n first-vm

1	lxc-create -t download -n first-vm

To list VM, use command lxc-ls

root@UNUSED:~# lxc-ls
first-vm 
root@UNUSED:~# lxc-ls -f
NAME     STATE   AUTOSTART GROUPS IPV4      IPV6 UNPRIVILEGED 
first-vm RUNNING 0         -      10.0.3.26 -    false        
root@UNUSED:~#

root@UNUSED:~# lxc-ls

first-vm

root@UNUSED:~# lxc-ls -f

NAME STATE AUTOSTART GROUPS IPV4 IPV6 UNPRIVILEGED

first-vm RUNNING 0 - 10.0.3.26 - false

root@UNUSED:~#

To start a VM, run

lxc-start VM_NAME

1	lxc-start VM_NAME

To login to a VM, run

lxc-attach VM_NAME

1	lxc-attach VM_NAME

lxc-create

lxc-create is used to create lxc container. To create a container, run

lxc-create -t download -n CONTAINER_NAME_HERE

1	lxc-create -t download -n CONTAINER_NAME_HERE

This will list all available containers. You can select the OS you want to use.
