Second Virtual Machines Not Starting.

Description

Scale: TrueNAS-SCALE-22.02.1

When Trying to start my second VM I get a failure: [EFAULT] Requested operation is not valid: PCI device 0000:18:00.0 is in use by driver QEMU, domain 1_UbuntuServer1

PCI Device:

18:00.1 Audio device: NVIDIA Corporation Device 228e (rev a1)

I noticed that in system setting this device keeps turning up as an isolated GPU Device. I can remove it, reboot, see it not there, start the VM and it reappears as an isolated device. I believe this is the issue, but I have NO idea how to remove this as an isolated device or change the VM, such that it doesn't keep readding this.

you are trying to use the same PCI device with multiple VMs at the same time. That won't work. So you can only use a PCI device with one VM at the time, so the error you are getting is valid. Please let me know if i have not followed you correctly perhaps. Thanks!

Thanks . I still feel like this is a lack of understanding on my part with KVM, virtualized GPU vs GPU passthrough.
