Added new NVME drive now VM won't start -

[Griz]

I added a NMVE drive and now my VM won't start.  I get the following email:

Quote

Event: VM Autostart disabled
Subject: vfio-pci-errors
Description: VM Autostart disabled due to vfio-bind error
Importance: alert
Please review /var/log/vfio-pci-errors

 

I managed to find /var/log/vfio-pci-errors:

/var/log# cat vfio-pci-errors
Error: Vendor:Device 10de:21c4 not found at 0000:05:00.0, unable to bind device
Error: Device 0000:05:00.1 does not exist, unable to bind device
Error: Device 0000:05:00.2 does not exist, unable to bind device
Error: Device 0000:05:00.3 does not exist, unable to bind device

 

I have no idea what any of this means...   How do I troubleshoot?

 

Edit:  I uninstalled the new NMVE drive and found in Tools->System Devices that 10de:21c4 is the GPU that is passed through to the VM....  still not sure why adding a SSD would break this and how to proceed.

Adding new hardware can change the IDs, you will need to adjust the passed through devices after.

I guess I need to remove the passed through GPU before adding the SSD?   Because after adding the SSD the passed through GPU does not appear in the VM config, so I don't see any way to change it in the UI.

Depends an how you are passing it through, generality you just need to go to Tools - System Devices, correct the devices being passed though and reboot, and then you may also need to re-adjust the VM config/XML.

I have it working again...    The devices re-appeared on System Devices when I removed the new SSD.  I unchecked them, edited the VM to not use the GPU.   Then reinstalled the SSD and reconfigured the passthru.

 

Thanks for the help, your insight lead me down the right path.
