Storage to VMs with Proxmox
(alien.top)
Also, I'll intend to do some NAS work, but I'll probably just end up doing NFS of some kind. You know, why would I spin up unraid to manage all the storage when I could spend a few days tuning NFS shares for 4 different OSes at home.
Just use zfs within proxmox, only reason you'd do disk passthrough to vm would be if you're using esxi and want to use zfs still.
Plus hardware pass through makes moving VMs more complicated. More virtual disks and networked storage for everything reasonable
