# Requirements

## Go

LXD requires Go 1.19 or higher and is only tested with the Golang compiler.

We recommend having at least 2GB of RAM to allow the build to complete.

## Kernel requirements

The minimum supported kernel version is 5.4.

LXD requires a kernel with support for:

- Namespaces (`pid`, `net`, `uts`, `ipc` and `mount`)

- Seccomp

- Native Linux AIO (`io_setup(2)`, etc.)

The following optional features also require extra kernel options:

- Namespaces (`user` and `cgroup`)

- AppArmor (including Ubuntu patch for mount mediation)

- Control Groups (`blkio`, `cpuset`, `devices`, `memory`, `pids` and `net_prio`)

- CRIU (exact details to be found with CRIU upstream)

As well as any other kernel feature required by the LXC version in use.

## LXC

LXD requires LXC 4.0.0 or higher with the following build options:

- `apparmor` (if using LXD’s AppArmor support)

- `seccomp`

To run recent version of various distributions, including Ubuntu, LXCFS should also be installed.

## QEMU

For virtual machines, QEMU 6.0 or higher is required.

## Additional libraries (and development headers)

LXD uses `dqlite` for its database, to build and set it up, you can run `make deps`.

LXD itself also uses a number of (usually packaged) C libraries:

- `libacl1`

- `libcap2`

- `liblz4` (for `dqlite`)

- `libuv1` (for `dqlite`)

- `libsqlite3` >= 3.25.0 (for `dqlite`)

Make sure you have all these libraries themselves and their development headers (`-dev` packages) installed.
