I’ve found the idea of LXC containers to be better than they are in practice. I’ve migrated all of my servers to Proxmox and have been trying to move various services from VMs to LXC containers and it’s been such a hassle. You should be able to directly forward disk block devices, but just could not get them to mount for an MinIO array - ended up just setting their entire contents to 100000:100000 and mounting them on the host and forwarding the mount point instead. Never managed to CAP_IPC_LOCK to work correctly for a HashiCorp Vault install. Docker in LXC has some serious pain points and feels very fragile.

It’s damning that every time I have a problem with LXC the first search result will be a Proxmox forum topic with a Proxmox employee replying to the effect of “we recommend VMs over LXC for this use case” - Proxmox doesn’t seem to recommend LXC for anything. Proxmox + LXC is definitely better than CentOS + Podman, but my heart longs for the sheer competence of FreeBSD Jails.

Actually I lied, according to the Dell manual the full profile slots have a connector that provides PCIe power though I’d have to buy a cable for it. Long term the answer might be to get a used V100 and dive deep into the vGPU rabbit hole (erp).

If you live by a major university, they likely have property disposition where you can pick up slightly older equipment, sometimes for super cheap.
