# Requirements

## Go

LXD requires Go 1.23.3 or higher and is only tested with the Golang compiler.

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

## Kernel requirements

The minimum supported kernel version is 5.15, but older kernels should also work to some degree.

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 or newer versions:

- 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)

- SKBPRIO/QFQ qdiscs (for `limits.priority`, minimum kernel 5.17)

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

## LXC

LXD requires LXC 5.0.0 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 6.2 or higher is required. Some features like Confidential Guest support require a more recent QEMU and kernel version.

Hardware-assisted virtualization (Intel VT-x, AMD-V, etc) is required for running virtual machines. Additional hardware support (Intel VT-d, AMD-Vi) may be required for device pass-through.

## ZFS

For the ZFS storage driver, ZFS 2.1 or higher is required. Some features like `zfs_delegate` requires 2.2 or higher to be used.

## 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` >= 3.37.2 (for `dqlite`)

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