I am trying to launch a Talos VM that I have running Plex and Fileflows and suddenly it will no longer boot, and I get the following error.
[EFAULT] internal error: qemu unexpectedly closed the monitor:
2025-04-26T06:01:18.913532Z qemu-system-x86_64: -accel kvm: warning: Number of SMP cpus requested (240) exceeds the recommended cpus supported by KVM (72)

When I edit the GPU section of the VM it says the address is [0000:af:00.0] but the error refers to [0000:af:00.1], so the address changed?
It seems as though it is similar to this issue: https://forums.truenas.com/t/docker-apps-and-uuid-issue-with-nvidia-gpu-after-upgrade-to-24-10/22547
So based on that, and other reports I saw in Discord and Reddit I ran the following command: midclt call app.gpu_choices | jq
The only thing it shows is the Matrox GPU, not the NVIDIA. So I’m not sure what’s going on
{
"0000:03:00.0": {
"vendor": null,
"description": "Matrox Electronics Systems Ltd. Integrated Matrox G200eW3 Graphics Controller",
"vendor_specific_config": {},
"pci_slot": "0000:03:00.0"
}
}
I removed the GPU and the VM wil boot, but it will constantly throw nvidia related errors until it reboots (roughly every 90-120min).
At this point I have no idea what’s going on. Is the card there or not? How do I remove the references to the nvidia card so if nothing else the VM will stop rebooting itself.
