Architectures

LXD can run on just about any architecture that is supported by the Linux kernel and by Go.

Some entities in LXD are tied to an architecture, for example, the instances, instance snapshots and images.

The following table lists all supported architectures including their unique identifier and the name used to refer to them. The architecture names are typically aligned with the Linux kernel architecture names.

ID	Kernel name	Description	Personalities
1	i686	32bit Intel x86
2	x86_64	64bit Intel x86	x86
3	armv7l	32bit ARMv7 little-endian
4	aarch64	64bit ARMv8 little-endian	armv7l (optional)
5	ppc	32bit PowerPC big-endian
6	ppc64	64bit PowerPC big-endian	powerpc
7	ppc64le	64bit PowerPC little-endian
8	s390x	64bit ESA/390 big-endian
9	mips	32bit MIPS
10	mips64	64bit MIPS	mips
11	riscv32	32bit RISC-V little-endian
12	riscv64	64bit RISC-V little-endian
13	armv6l	32bit ARMv6 little-endian
14	armv8l	32bit ARMv8 little-endian
15	loongarch64	64bit LoongArch

Note

LXD cares only about the kernel architecture, not the particular userspace flavor as determined by the toolchain.

That means that LXD considers ARMv7 hard-float to be the same as ARMv7 soft-float and refers to both as armv7l. If useful to the user, the exact userspace ABI may be set as an image and container property, allowing easy query.

Virtual machine support

LXD only supports running virtual machines on the following host architectures:

• x86_64

• aarch64

• ppc64le

• s390x

The virtual machine guest architecture can usually be the 32bit personality of the host architecture, so long as the virtual machine firmware is capable of booting it.
