I just purchased a 1L PC to replace my current Docker server (Synology NAS). I mostly host all my services via Docker. But I do plan on trying out some VMs for more remote desktop type stuff not for hosting services.

The 1L PC is a HP Elite Mini G9. I will be adding 2 SSDs for redundant OS disks. And I will be utilizing my Synology NAS for storage. So the 1L PC doesn't need crazy amounts of storage and I will not be using it like a NAS.

Which OS should I use as the basis of the 1L PC? I like the idea of the easy nature of TrueNAS as a base OS, so I can set up shares and permissions easily. But do VMs run well under TrueNAS? Is there another OS I should consider as the basis of this mainly Docker server with some VMs?
