Do you have suggestions on what I should do to make
this yield_to functionality work?
Keeping in mind the complications of yield_to, I had suggested we do something
suggested below:

Essentially yield to other tasks on your own runqueue and when you get to run
again, try reclaiming what you gave up earlier (with a cap on how much one can
feedback this relinquished time). It can be accomplished via a special form of
yield(), available only to in-kernel users, kvm in this case.
I don't see how that is going to help get the lock
released, when the VCPU holding the lock is on another
CPU.
