So originally I passed through 03:00.0 and 03.00.1 and add PCI deivces but still couldnt could drivers to work, was as if the gpu wasnt even associated when using VirtualGL:
So attempted now removing 03.00.1 from the qube and now get error:
Unable to reset PCI device 0000:03:00.0: internal error: Active 0000:03:00.1 devices on bus with 0000:03:00.0, not doing bus reset, see /var/log/libvirt/libxl/libxl-driver.log for details
Would I need to revert the passthrough of 03.00.1 as it is in a separate group to fix this error to get the GPU to work?
