[Physical push button to start a VM?]

That would be awesome!
Do you also need a docker in unraid that the RPi sends its command to?

No; it just sends a request to the Unraid server. It doesn't utilize the Unraid Electric Brain API or whatever it's called. But if you wanted to PM me your discord (for easier method of communication) I can give you a shopping list of stuff that you'll need, or whether you already have the necessary items.

[Physical push button to start a VM?]

Hey!

 

I actually use a pushbutton switch to power on/off my virtual machine. If you've got an RPi I can share my code with you (wouldn't be too hard to replicate for an Arduino). I use an RPi Zero that connects to WiFi and just sends a request to my Unraid server.

@LiableLlama would vfio binding the audio in my iommu group work for passing through or does it have to be in a separate group on its own

 

IOMMU group 10:

[1022:1482] 00:08.0 Host bridge: Advanced Micro Devices, Inc. [AMD] Starship/Matisse PCIe Dummy Host Bridge

[1022:1484] 00:08.1 PCI bridge: Advanced Micro Devices, Inc. [AMD] Starship/Matisse Internal PCIe GPP Bridge 0 to bus[E:B]

[1022:1485] 0e:00.0 Non-Essential Instrumentation [1300]: Advanced Micro Devices, Inc. [AMD] Starship/Matisse Reserved SPP

[1022:1486] 0e:00.1 Encryption controller: Advanced Micro Devices, Inc. [AMD] Starship/Matisse Cryptographic Coprocessor PSPCPP

[1022:149c] 0e:00.3 USB controller: Advanced Micro Devices, Inc. [AMD] Matisse USB 3.0 Host Controller

[1022:1487] 0e:00.4 Audio device: Advanced Micro Devices, Inc. [AMD] Starship/Matisse HD Audio Controller

You can bind it and it should work. Although, if it does not you can enable ACS PCIe Override and see if that makes any difference. It can cause weird issues though, usually it all works fine.

Mine does the same thing, the first CPU core for that VM goes to 100% and then crashes, what logs would you like ?

Could you post the VM log, VM XML and IOMMU groups? Also, do you have PCIe ACS Override enabled? My issue was with macOS High Sierra. I had fixed it by turning off PCIe ACS Override and adding the device ids of my PCIe devices to the vfio-pci.ids param of the syslinux configuration.

Main -> Flash -> Syslinux Configuration -> Unraid OS

Change the following device id(s), where 0000:0000, 0001:0001 are your device ids. To add more than these two just add another comma following the last device id. If you can't find your device id(s), post your IOMMU groupings and I'll take a look.

append vfio-pci.ids=0000:0000,0001:0001 initrd=/bzroot

Could you post any logs if possible? Aswell, when the issue occurs could you take notice of the CPU usage? I was having a similar issue but not with a soundcard and when it happened the CPU usage on a single core spiked to a fixed 100%
