Go¶
LXD requires Go 1.22.0 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,ipcandmount)Seccomp
Native Linux AIO(
io_setup(2), etc.)
The following optional features also require extra kernel options or newer versions:
Namespaces (
userandcgroup)AppArmor (including Ubuntu patch for mount mediation)
Control Groups (
blkio,cpuset,devices,memory,pidsandnet_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, LXCFSshould also be installed.
QEMU¶
For virtual machines, QEMU 6.2 or higher is required. Some features likeConfidential Guest support require a more recent QEMU and kernel version.
Hardware-assisted virtualization (Intel VT-x, AMD-V, etc) is required forrunning virtual machines. Additional hardware support (Intel VT-d, AMD-Vi) maybe required for device pass-through.
ZFS¶
For the ZFS storage driver, ZFS 2.1 or higher is required. Some featureslike 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 canrun make deps.
LXD itself also uses a number of (usually packaged) C libraries:
libacl1libcap2liblz4(fordqlite)libuv1(fordqlite)libsqlite3>= 3.37.2 (fordqlite)
Make sure you have all these libraries themselves and their developmentheaders (-dev packages) installed.
