[PATCH v6 00/10] kvm: x86: migration of nested virtualization state

[Paolo Bonzini <pbonzini@redhat.com>]

This is the next version of the nested virtualization migration series,
now with unit tests too.

Patches 6, 7, and 9 replace the (broken) WIP patches in the kvm/queue branch,
while the other seven are new and related to the tests.  In particular, patch 1
is an independent bugfix, which makes it much simpler to use KVM_GET_MSR/KVM_SET_MSR
in a simple userspace client such as the new test.  Patches 2-4 are also
improvements and bugfixes to the unit test infrastructure.

Please review (especially the non-test patches of course!).

Thanks,

Paolo
