I have an issue creating VMs on my Unraid Server -

I have added 32GB RAM to my DELL T30 but I get the following error when creating a VM:

internal error: qemu unexpectedly closed the monitor: qxl_send_events: spice-server bug: guest stopped, ignoring
2022-06-11T07:43:52.752062Z qemu-system-x86_64: -device vfio-pci,host=0000:00:1f.3,id=hostdev0,bus=pci.0,addr=0x6: vfio 0000:00:1f.3: group 7 is not viable
Please ensure all devices within the iommu_group are bound to their vfio bus driver.

I am pretty new to VMs on Unraid but it looked straight forward.

Can you give me some advice ? or point me in the right direction ?

Thank you in advance,

Best regards,

Harald

Issue is with audio at 00:1f.3 you are trying to passthrough.

You attached nothing to vfio at boot, all devices that you want to passthrough should be attached to vfio at boot.

Currently, audio is in the same iommu group with:

00:1f.0 ISA bridge [0601]: Intel Corporation C236 Chipset LPC/eSPI Controller [8086:a149] (rev 31)
	Subsystem: Dell Device [1028:07c5]
00:1f.2 Memory controller [0580]: Intel Corporation 100 Series/C230 Series Chipset Family Power Management Controller [8086:a121] (rev 31)
	DeviceName: Onboard SATA #1
	Subsystem: Dell Device [1028:07c5]
00:1f.3 Audio device [0403]: Intel Corporation 100 Series/C230 Series Chipset Family HD Audio Controller [8086:a170] (rev 31)
	Subsystem: Dell Device [1028:07c5]
00:1f.4 SMBus [0c05]: Intel Corporation 100 Series/C230 Series Chipset Family SMBus [8086:a123] (rev 31)
	Subsystem: Dell Device [1028:07c5]
	Kernel driver in use: i801_smbus
	Kernel modules: i2c_i801

 

You may want to apply the acs override patch in unraid to see if it can break iommu group 7 and separate the audio.

 

Or.....do not passthrough audio at all.

Thank you I disabled audio for now - will have a look if the other solution yields a result later . Thank you
