LXC is very useful. I've ran both containers and VMs using LXC (yes including a windows VM) issues is that it's it's great for creating and testing systems locally but it's intentionally a total pain in the posterior to "expose" a container to the network. I did use a rpi3b running alpineOS to run a few basic containers I could access from the internet to test things.

I recently set up an dedicated game server for the game Enshrouded in Proxmox, alas it's pretty resource hungry. My first try in a VM was very disappointing. I have an Ryzen 4300G running my homelab and i gave the VM 8 vCPUs (so one for each physical thread) and 16 GB RAM. The gaming experience for one connected player was O.K'ish but for three ore more it was unusable. I then switched to a (privileged) LXC also 8 vCPUs but only 8 GB RAM (the game is more CPU than memory hungry). The gaming experience is much(!) better. Now gaming with 3 or 4 players is possible. Nonetheless the Enshrouded dedicated Server is pretty bad performing it consumes almost half of my Homelab which was not the case with other game servers like Valheim e.g.! But yes there are performance gains when using LXC in such "extreme" situations!

Amazing guide as usual. One question, is it possible to pass through individual disks to an lxc, not just mount point, the entire hard disk?

@Jims-Garage 3 ай бұрын

Yes, albeit I think we need to be careful with wording. My understanding is that you're giving the LXC access to the device, not passing it through like a VM. As such, the host can see it as well as other LXCs if you allow it. This is how I'm able to share a single GPU with 3 LXCs.

@@Jims-Garage i was also able to pass through my nvidia gpu to lxc using cgroups in the .conf file, the thing is the same method would not work for disks for some reason, the disk just wont be listed under /dev/disk/by-id/ , if you had any luck please pass the knowledge.

Excellent. Question: how much thinner is an LXC vs a VM? That is to say, if a Debian install as a VM is X megabytes, how much smaller is the LXC install?

About 20x smaller

Well I have a SMB server with Webmin on 81k of ram , netboot-xyz on 81k , and jellyfin on 374k , so most programs only need 512k or less , try running a running jellyfin on a 512k VM .

Nice! My only concern here is how the lifecycle is. When using docker I have watchtower for many of my containers and for the critical ones it is just a manual docker compose pull (or the Portainer GUI). Let's say a move them all to individual LXC containers. Now what? I've seen many of these videos, but no one addresses this important fact. Cheers!

No, install docker on LXC. Use docker as normal

@fedefede843 3 ай бұрын

@@Jims-Garage that is ok. That could be the best of both worlds. I have read different opinions on installing docker on LXC, but I guess it is a matter of trying it. Do you use it like that or have docker on top of a VM? In my case if I am going to have most of my services in a single environment, it could be just a VM. Since I am not splitting out too much else, why bother. I haven't reached the kubernetes world yet, but I'm looking forward to it. Cheers

One problem you may hit if you are on AMD and passing hardware acceleration to jellyfin or frigate , to pass your GPU with PCIe passthrough you blacklist nvidia and radeon , amdgpu drivers etc. So stopped the hardware acceleration from the GPU until I removed the radeon & amdgpu from the blacklist.

@pabloszi 3 ай бұрын

Hmmm... With LXC you don't need to passthru PCI-e devices. You can share it between your desired LXC, Proxmox OS and other LXCs you want.

@@pabloszi you don't , BUT if you do pass a full PCI-e device to a VM don't disable the inbuilt iGPU at the same time. I pass iGPU hardware encoding / decoding to a Frigate & Jellyfin LXCs , but have a VM with my RTX2070 super to use for tdarr.

@pabloszi 3 ай бұрын

@@peteradshead2383 That's right. It works as you described with VM, but LXC isn't VM. LXC is Linux container, and you can't passthru PCI cards to LXC. Instead of this you can share devices between Proxmox host and LXCs.

I have started with Proxmox with VMs only as it was much easier to work with (for the newbie like me). But now, I move almost everything to LXC. Lighter but most importantly: I feel much better with IP management - rather than assigning MACVLAN in docker (in VM). Sharing the storage sometimes is an issue but once you know how to it is easy. But still there is a place for VMs there.
