Gaming VM crashes Unraid server when I try VR

[cerlendson]

I've created a Windows 10 VM that's passing through an AMD 6650xt and for the most part everything runs great. Games run as expected except when I try connect my Meta Quest 3 to SteamVR (wirelessly)... Unraid reboots every time.

 

I've added the following to my Syslinux Configuration:

video=efifb:off
pcie_no_flr=1022:149c,1022:1487

 

I've bound the GPU and GPU audio to the VFIO at boot.

My VM passthrough look like this:

 

<hostdev mode='subsystem' type='pci' managed='yes'>
      <driver name='vfio'/>
      <source>
        <address domain='0x0000' bus='0x03' slot='0x00' function='0x0'/>
      </source>
      <rom file='/mnt/user/share/isos/vbios/6650xt.rom'/>
      <address type='pci' domain='0x0000' bus='0x23' slot='0x00' function='0x0' multifunction='on'/>
    </hostdev>
<hostdev mode='subsystem' type='pci' managed='yes'>
      <driver name='vfio'/>
      <source>
        <address domain='0x0000' bus='0x03' slot='0x00' function='0x1'/>
      </source>
      <address type='pci' domain='0x0000' bus='0x23' slot='0x00' function='0x1'/>
    </hostdev>

 

Any suggestions would be VERY appreciated.

Create a syslog server to see if any logs before reboot
