I am mostly concerned with migrating between qemu versions with different roms, while guest was in the middle of running ROM. This might be solved if we migrated ROM content together with the device and put some padding in ROM content so that size can be kept constant.
SeaBIOS will always copy the roms into the 0xc0000-0xf0000 memory area (regardless of CONFIG_OPTIONROMS_DEPLOYED). So, if one migrates a machine while running a rom, the memory holding the rom should get migrated with everything else.
Yes, but if migration happens in the middle of the copying...
Yes. This is not a new bug though.
How so?
