When using the qemu-0.15.1 with -nographic and a typical OE image, you
will get a segmentation fault in v86d when the guest OS is booting.
It will look like:
v86d[42]: segfault at 0 ip 000000000040171a sp 00007fff5d11bad8 error 4 in v86d[400000+1a000]
Sometimes this is fatal to the guest, sometimes it is not, either way
it was fixed by the upstream qemu commit: 6023d832480e6713e5ae81d3b74f53e6306f3a1b
(disable automatic loading of sgabios when -nographic)

+Subject: [PATCH] disable automatic loading of sgabios when -nographic
+
+sgabios hasn't gotten a lot of coverage since it was not shipped. For 1.0,
+let's disable the automatic loading of the option ROM in -nographic
+mode. We can put it back for 1.1.
