Good evening all,

Thanks for the answer, but I am afraid it does not work for my case. If I read this correctly it is used for hostdev devices, so devices that get passed through from
the host to the guest. I need to introduce the "rom_bar=off" attribute to a virtual driver.

E.g.

    <interface type='bridge'>
      <mac address='52:54:00:0b:db:64'/>
      <source bridge='br0'/>
      <model type='virtio'/>
      <address type='pci' domain='0x0000' bus='0x00' slot='0x02' function='0x0'/>
    </interface>

must become:

    <interface type='bridge'>
      <mac address='52:54:00:0b:db:64'/>
      <source bridge='br0'/>
      <model type='virtio'/>
      <address type='pci' domain='0x0000' bus='0x00' slot='0x02' function='0x0'/>
      <rom bar='off'/>
    </interface>


Preferably by adding an extra option during virt-install. Is this possible?

Many thanks for your help!

Kind regards,
