3VM's & 3GPU's Issues and troubles

[monk100]

The End Goal:

A gaming rig with 3 (windows 10) vm's, each with a dedicated GPU.

 

The Setup:

-UnRAID 6.1.9 - Only using this server for gaming VM's.  No other plugins installed.

-Motherboard (Asrock z77 extreme 6) & CPU (i7 3770) are vt-d compatible (needed for immou) and the feature is enabled in the bios (Tested with 2 different bios revisions, currently on the newest).  UnRaid reports "Enabled" beside HVM & IOMMU.

-GPU's 2x 960's, 1x 750ti.  (Also tested with amd 6870, 560gtx, 9500gt)

 

The Issue:

When setting up the third VM w/ GPU pass through the UnRaid host crashes when installing the nvidia drivers.

 

What trouble shooting have I done?

-Installed win10 as the main OS.  Confirmed that all three video cards show up and work as expected (so I know the motherboard is in working condition).

-Swapped in a different power supply.  Corsair 1200i.  No change.

-These are new installs of Windows 10.

-Tested with different machine types i440fx to Q35, etc

-Tested with OVMF... had little luck even getting it to boot after 3-4 OS reboots.

-Tested different Nvidia WHQL driver versions.

-Tried mixing up the video cards in different motherboard slots.

-Tried disabling every non-essential device in the bios.  (Firewire, usb3, comm)

-I have done more...just can't remember *all* of it.

 

Any help would be extremely appreciated.

Updating to 6.2.0 beta21 solved all my issues.

I can now run 3 windows 10 vm's each with a GPU passed through.

 

Notes:

All three are running on OVMF.  i440fx-2.5
