Jason, after a long conversation I've had with Michael during the
previous week, we reached some common points:

1 - We believe it is possible to be able to both log in *and* log serial
console output. That will require changes to kvm_subprocess and might
take a little bit more time.
2 - We know you guys are depending on this patchset to be accepted in
order to proceed with the network related cases. However, we ask for a
little more patience, and we'd like to get your opinions on the patches
that we are going to roll out. This way we can get to a better solution
for all of us.

So, please bear with us and I'll try to see with Michael and Dor if we
can prioritize this work to not block work items for you guys.

Cheers,

Lucas
