Nested virtualization on x86 is finally becoming a thing: lots of work has been
done recently to eliminate bugs and make it faster. Testing, however, remains
a challenge and regressions even for KVM-on-KVM are, unfortunately, not
uncommon. Adding third party hypervisors (Hyper-V, VMware,...) and different
types of L2 guests to the picture also doesn't make it any simpler.

The talk will try to cover the existing KVM testing frameworks: kvm-unit-tests
and selftests, what these frameworks test and what they don't, the gaps we have
between VMX and SVM. Possible improvements and additional testing approaches
will be suggested. Overall, this is going to be an open discussion on how we
can test nested virtualization better.
