  1. Until 2 days ago, I had things running (mostly) the way I wanted with 2 nvidia GPUs passed through to 2 separate windows VMs. I was unable to connect to those machines sometime yesterday, but was able to connect to other VMs without any issue. I was able to access those machines after rebooting the server. When the machines went down again randomly today, I rebooted the server, but only started up 1 of the VMs with passed through GPU, and it worked fine - but lost connection again a few hours later. I tried to start up the other VM (with passed through GPU), and it's now throwing up the below error internal error: Unknown PCI header type '127' for device '0000:01:00.0' Interestingly, the CPU for the VM that I cannot access is stuck at 100% Has anyone else come across this?
  2. Interesting question. So - I swapped in a 5700 instead, and had all the previous issues. I then watched @SpaceInvaderOne's video on how he passed through his 5700XT and made the following changes - I tried q35+ovmf - I passed through a bios that I downloaded from techpowerup....... And it worked! Managed to install drivers etc, and then rebooted. Blank screen again! I figured it was the AMD reset bug - so I tried @SpaceInvaderOne's script to reset the card without rebooting the server, and it got as far as putting the server to sleep. I could not wake the server up, so had to reset which ended up causing errors on my parity drive (now rebuilding) and and caused a few issues with some of my other VMs, so am trying to recover those before trying again. Any advice for the next attempt?
  3. Argh. Swapped a different GPU in - same problem, including the inability to dump bios. I have a feeling I am missing something relatively minor here....
  4. So I have been doing more reading, and this led to the bright idea that I should try dumping my ROM to help with the passthrough. I tried spaceinvader ones script etc - but it just simply doesn't work. I wonder if my card is a lemon. Pity I don't have a spare box to do some more testing. That said - I will try and swap a different GPU in and see if I get any joy that way. Thanks for your help.
  5. Thank you for your suggestion - it is much appreciated. What does the multifunction option offer? - I tried it, but still no luck. Any suggestion on where to from here? I have checked my disks - now passing all tests.
  6. Hi all, Hoping someone will be able to assist. I have a unraid server with three graphics cards - 1st slot has a nvidia GT710 - 2nd slot has a AMD RX6700XT - 3rd slot has a nvidia 3080 I have successfully passed through the 3080 to a win10 VM with no issues. I am struggling to pass through the 6700XT to a separate win10 VM. I normally connect to my VMs via RDP, and it works ok when the 6700XT is not passed through, but times out when the 6700XT is passed through. Interestingly, I have installed nomachine on the Win10 vm, and it shows up as 'available' on the network - but times out when I attempt to connect. I have attached my diagnostics - the first is with the 6700XT not passed through, and the second has the 6700XT passed through. Thanks. odin-diagnostics-20220103-0816.zip odin-diagnostics-20220103-0842.zip
