I've been using Unraid for a few months. It has a different - arguably inferior - parity strategy but has amazing support for VMs. I've got my gaming machine, my GPU dev box and a bunch of smaller services all in the same box and can do some really sweet online configuration.

How is it for gaming? I'd imagine it's using a VM solution (Xen HVM or KVM so it can do IOMMU?). I've been avoiding it because I figure that VM solution would get detected by anti-cheat in many games (particularly the nasty kernel level ones like EasyAntiCheat, GameGuard, etc).

I have 8x2.8 ghz Xeon cores 32 GB of RAM and a 970 GTX in my gaming vm. Works perfectly for DOOM, Witcher 3, all at 1920x1080 on high settings (maybe not full but damn pretty). Consensus on the forum seems to be you lose low single digit performance.

It's a KVM hypervisor and I haven't played online, why would they ban you for using a VM?

A VM makes it possible to arbitrarily read and modify memory from outside of the operating system in a way that the anti-cheat can't otherwise detect (heck, some VMs have full out integrated debuggers), so anti-cheat and DRM schemes used by games may disallow VMs.

I've been thinking about switching my home NAS to UnRAID. The parity sounds great and BTRFS RAID5/6 just doesn't seem to be in a good state right now.
