No, it does not give me that error from cold boot, however the device also does not appear to be functional in the first run of the VM.

Hello, I recently build an unRAID server with the intention of also using it to run a VM to serve as a secondary PC for streaming. I was successfully able to pass through a Black Magic Intensity Pro 4k, however the card itself was performing unsatisfactorily, so I returned it in lieu of a Elgato HD60 pro, however the same techniques are proving to be ineffective for passing through this other capture card. 01:00.0 Non-VGA unclassified device: Yuan Yuan Enterprise Co., Ltd. Device 0380 (rev ff) Is the associated line from a lspci call, and with the -n flag: 01:00.0 0000: 12ab:0380 (rev ff) I have add the pci-stub.ids=12ab:0380 line to the syslinux and added the following to the VM's XML: <hostdev mode='subsystem' type='pci' managed='yes'> <driver name='vfio'/> <source> <address domain='0x0000' bus='0x01' slot='0x00' function='0x0'/> </source> </hostdev> When attempting to start the VM, the following error(s) appear: internal error: early end of file from monitor: possible problem: 2016-02-17T05:36:22.229030Z qemu-system-x86_64: -device vfio-pci,host=01:00.0,id=hostdev3,bus=pci.0,addr=0x7: vfio: Error: Failed to setup INTx fd: Device or resource busy 2016-02-17T05:36:22.229498Z qemu-system-x86_64: -device vfio-pci,host=01:00.0,id=hostdev3,bus=pci.0,addr=0x7: Device initialization failed 2016-02-17T05:36:22.229516Z qemu-system-x86_64: -device vfio-pci,host=01:00.0,id=hostdev3,bus=pci.0,addr=0x7: Device 'vfio-pci' could not be initialized I have attempted with and without ACS override and cannot think of anything else to try and was wondering if anyone had some suggestions?
