[Qemu-devel] Command line option "-option-rom" doesn't take the ROM file

[Qemu-devel] Command line option "-option-rom" doesn't take the ROM file

[Deema B]

Hi,

I'm trying to use the -option-rom option to supply my own virtio OpROM.

I am not able to see the ROM being launch (the built-in version comes up
instead).
The only way I am able to make it work is to rebuild the Qemu and iPXE
together.

I'm assuming this is working feature, and I'm simply doing something wrong.
Appreciate any suggestions, pointers, and to hear your experience with this
particular option.

Hi Deema,
You can specify the option ROM on a per-device basis:

  -device virtio-net-pci,romfile=my-ipxe.rom,...

The advantage of this approach is that there is no conflict between the
global -option-rom file and the default file loaded by the NIC device.

I replied to the other copy of this email.  Sometimes the mailing list
is slow to process mails but in almost all cases it will eventually
process them.  Please only send one copy of your emails to the mailing
list.

Thank you, Stefan!  That worked.
Sorry for the double email, I'm learning quickly :)
