I did a quick look. The runtime apparently uses the -bios option when the firmware option is passed, not the -drive option as I thought it would. I'm not entirely sure you can boot OVMF that way. I don't have any idea at the moment why it worked with version 1.x. If you could share with me the 1.x qemu command line option with the firmware option, I'm curious to see what it is.

Thanks
