This patchset adds an API test framework. Rather than driving kvm from qemu,
we now have a way of calling the kvm API directly and observing the results.
We can switch to guest mode and back at will and see any micro effects such
as the result of executing particular instructions.
A first test is added, for commit edde99ce0 ("KVM: Write protect memory
after slot swap"). This would be pretty hard to test for using the current
qemu-driven tests, but detects 5 million failures in about two minutes on
my machine.
As an experiment, the framework is coded in C++.
