[PATCH] conn: Pretend to be a serial terminal, so sgabios doesn't hang.
This tedious workaround avoids a 0.26 second pause when using sgabios (the Serial Graphics Adapter).

Standard seabios doesn't support serial line (well, it was quite a while ago that I've tested this and it didn't back then, maybe things have changed since then).

way to see the bootmenu via serial?
Maybe this should go to the qemu mail list, but I have domains configured to dump to serial. Works fine I see Grub menu/kernel messages and the like, but the "bootmenu" listing only shows up over vnc. Is there a way to have that show up over serial? I definitely can hit up the qemu mail list as well if inappropriate for here
