[Compatibility with external eGPU's]

Has there been anyone who has attempted to run unraid with virtual machines against external GPU's using thunderbolt?

I would also like to know about compatibility with laptops that may be able to use the thunderbolt ports for VM assignments.

After doing some snooping I found that there were 2 more USB 3 ports available on my motherboard under the ethernet slot that I was able to plug into the 1st vm. I can now play occulus on both VM's at once. Time to setup echo VR.

Re-tested USB Occulus headset playability and got through a whole song in Beat Saber before hearing a high pitched beep then the game froze and went black. The whole time it had a very static-y fuzz to all the audio as well.

VM starts no problem when card is deselected.

Posting updated tower diagnostics. I have attempted the following with no luck:

 

- Q35- 4.0.1

- Q35- 4.1

- USB Controller - 3.0 qemu

- USB Controller - 3.0 nec

Same behavior after update to 6.7.2.

 

Edit: Just saw your post, pushing up to 6.8.0-RC9 now, and making other recommended changes.

No reason for 6.6.0 other than not clicking update. I have made the suggested syslinux config changes and rebooted. I see the IOMMU groups much more spread out and I am able to assign the device to the VM. However, when the VM starts the attached screenshot and nothing else. I will attempt the upgrade now and see if that helps.

Here's the diagnosti cs, I did try to pass through the chipset USB controller but had connectivity issues with one of them. Here's what I've done

 

1. Setup 2 VM's with Windows 10

2. Attach a USB controller to each

     a. 2 of the 5 controllers (that are not in group 13) are assignable

     b. 1 of those 2 work perfectly for what I need. 

     c. the other has connectivity issues

          i. attached USB controller and started VM

          ii. connected Occulus Rift S to the assigned slots

          iii. Occulus device drops intermittently during setup, rendering it unusable

 

3. purchase USB card

4. have difficulty assigning USB card

     a. cannot isolate from IOMMU group 13 with acs overrides

     b. cannot utilize "downstream,multifunction" overrides for some reason because VM won't start after USB card assignment

I tried with overrides set to multifunction and downstream which did separate out the IOMMU group, but the VM will not start up correctly when I attach the device. The VM just shows the splash screen of the open source framework. Once I unassign the USB controller it is able to start into windows no problem. I don't see any errors in the VM logs. Any suggestions on how to proceed?

I have added a 4 port USB card to my unraid setup to allow VM assignment but I'm having difficulty breaking the new device out of the primary motherboard IOMMU group. Here is what I see when I plug in the device:

 

IOMMU group 13:[1022:43ba] 01:00.0 USB controller: Advanced Micro Devices, Inc. [AMD] X399 Series Chipset USB 3.1 xHCI Controller (rev 02)

[1b21:2142] 08:00.0 USB controller: ASMedia Technology Inc. ASM2142 USB 3.1 Host Controller

 

1912:0014 is the id for the device and I've attempted to isolate it on the Syslinux configuration:

 

kernel /bzimage
append amd_iommu=on iommu=pt iommu=1 pcie_acs_override=downstream vfio-pci.ids=1912:0014 vfio_iommu_type1.allow_unsafe_interrupts=1 initrd=/bzroot,/bzroot-gui

 

I am unable to assign the device to the VM because the rest of the devices do not apply. What can I do?
