LXD storage driver

[nealef]

Using the dir storage driver appears to be the worst option. Check https://documentation.ubuntu.com/lxd/en/stable-5.0/reference/storage_drivers/. I think we should explore lvm thin pools to optimise start up etc.

Yeah, we did some research over this a while ago and decided (not conclusively, we're still open to other options) to use LVM (with a ZFS storage driver) pool. We haven't worked on tweaking / fine-tuning the configs for our workloads so that is one thing which could show better results.
