Hey, every friend. I have a question. My guests are not working, unbelievable.

I can use it the first time I use it. But after I close my guest and start over, my guests will not appear. My screen is black.

My environment:

Guest: windows 10

vm-bios: ovmf

host: ubuntu 1604

qemu: 2.12

libvirt: 4.2

kernel: 4.17.2

xml config:

gpu:

<qemu:commandline>

<qemu:arg value='-device'/>

<qemu:arg value='vfio-pci,host=0000:01:00.0,romfile=/root/rom.file,multifunction=on,x-vga=on'/>

</qemu:commandline>

features:

<kvm>

</kvm>
