- if you have a good hardware , you can easily build digital ocean / aws lightsail like environment with a single install in 5 mins of configuration - A VPS Like experience for both Containers and QEMU

- Quick and easy multi-tenancy

- Very easy to build development enviorment isloated from the system.

- Isolation host for docker containers.

- Automatic networking support with DHCP , OVN or MacVLAN if you have multiple physical IPs.

- Home Made Cluster of containers.

It is literally best way to host multiple docker containers. Isolated from each other.

You wont need K8s in many case , infact if you don't have 10k+ users , do not need to worry about 99.999 uptime and redundancy - LXD is all you need.

Or if you have only one Physical Machine and want to test K8s cluters , you can use LXD Containers for that instead of resource intensive VMs.

I use it a lot for personal homelab infrastructure. I find it feels a lot more natural than single process containers for the workloads I use (torrent clients, game servers, plex...). I've unfortunately never used it for production workloads, and likely never will after recent news.

I also find lxc system containers better than OCI style immutable containers for dev environments for my personal projects, and LXD is the best way to manage them AFAIK.

Can I ask what people do without LXD?

It's the closest I've found to Linux-VServer which I still miss to this day.
