Hello guys,

this drives me insane. I am trying to pass romfile of my GPU for UEFI boot

This is an error I am getting :

[root@brutus-coreos opt]# virsh start winos1
error: Failed to start domain winos1
error: internal error: early end of file from monitor: possible problem:
2016-02-07T16:56:09.358285Z qemu-system-x86_64: -device
vfio-pci,host=01:00.0,id=hostdev0,bus=pci.0,addr=0x6,romfile=/opt/MSI.R9380.4096.150713.rom:
failed to find romfile "/opt/MSI.R9380.4096.150713.


The file is there , even owned by qemu

[root@brutus-coreos opt]# cd /opt
[root@brutus-coreos opt]# ls -lsa
total 136
  4 drwxr-xr-x.  2 root root   4096 Feb  7 17:53 .
  4 dr-xr-xr-x. 18 root root   4096 Feb  4 18:58 ..
128 -rw-rw-r--.  1 qemu qemu 131072 Feb  7 17:53 MSI.R9380.4096.150713.rom

I have tried to put it into /var/lib/libvirt/images or /usr/share/qemu ,
but it ends with the same error.

This is my libvirt XML
