Hello, I'm facing of a strange phenomenon, if someone can explain me : I'm starting a vm ( Windows guest) with intel igd passthrough :
<hostdev mode='subsystem' type='pci' managed='yes'> <source> <address domain='0x0000' bus='0x00' slot='0x02' function='0x0'/> </source> <address type='pci' domain='0x0000' bus='0x00' slot='0x02' function='0x0'/> </hostdev> It"s working well, the Vm is booting, display a standard Vga boot ( windows logo ) , then after sometime windows detect intel card and change resolution. Now, i've dump igd rom ( /sys/devices/pci0000:00/0000:00:02.0/rom ) and i'm starting the Vm with : <hostdev mode='subsystem' type='pci' managed='yes'> <source> <address domain='0x0000' bus='0x00' slot='0x02' function='0x0'/> </source> <address type='pci' domain='0x0000' bus='0x00' slot='0x02' function='0x0'/> <rom file='/data/romIgd'/> </hostdev> it's working but, the Vm is booting, then the screen seems to be pass into standby mode, then after sometime windows detect intel card and screen is ok. So my question is : When no rom file is provide, qemu load a standard vga bios before ? then load rom ?
