For what it is worth, I'm not sure sending debug/error messages to the
vga screen is a good long-term plan.  I fear it will be more
frustration than help to users.  Sure, having the VM not start isn't a
fun experience, but I'm not sure a weird cryptic error message that
flashes on the screen for a split second is an improvement.

Enabling the seabios log from qemu is an annoying step to have to
take, but I suspect taking that step may ultimately be necessary in
many cases.

Cheers,
-Kevin

It surely doesn't make sense for most errors, patch #2 switches over
only the errors for unsupported blocksizes.  That actually happens
in practice.  And when the VM doesn't boot the message will typically
continue to be displayed ...

take care,
  Gerd

I understand.  For what it is worth, I'm still unsure this is a good
long term plan though.
