Let me know if there is additional information that is needed. I'm thinking some may be userspace qemu-system-x86_64 issues since three of them can be resolved by adding "-cpu host"; however it may be something to add in the test-suite. Let me know and I am happy to write a patch depending on what you think will work. All tests below are done with the kvm tip (fresh as of today) merged with 3.16-rc4.
