Aoostar WTR series is one change away from being the PERFECT home server/nas. Passing the storage controller IOMMU to a VM is finicky at best. Still better than the vast majority of devices that don't allow it at all. But if they do that, I'm in homelab heaven. Unfortunately, the current iteration cannot due to a hardware limitation in the AMD chipset they're using.
Good info! Is it the same limitation on WTR pro and max? The max is an 8845hsv versus the 5825u in the pro.
