Darn, this should have been sgabios: /usr/share/sgabios/sgabios.bin
but if your seabios is new enough (v1.11.0 and newer) then this is not 
needed as seabios itself is capable of serial interface. And looking at 
earlier e-mails in the thread you have v1.12.0-1 you you're good and 
don't need to add <loader/> at all.

But honestly, I don't know why you are not getting the console. Could it 
be that you are getting the console and the qemu is waiting for your 
input, i.e. what happens if you type in the password?
