Hmmm, on my ubuntu 16.04 guest, I get the boot menu with no timeout even if I

I can reproduce this now, too. FWIW: It only happens with
virtio-blk-ccw, not with virtio-scsi-ccw (that's why I did not notice it
first). Collin, can you reproduce this, too?

The idea is to support the zipl boot menu on ECKD disks (which have a timeout 
by themselves)
even without switching the boot menu on. This is to have the same behavior as 
one would see
on LPAR or z/VM.
The issue is that the boot code tries to interpret the program table of SCSI 
bootmaps as if
a boot menu has been specified.
Ok, thanks for the explanation, makes sense now.

Collin, could you please spin a v9 with the required changes included?


I see.  I overlooked that we could treat a SCSI device as a CCW device.  The proposed change makes sense.
I'll respin 9 and reply to this chain.
