This is VMX version of the same issue as I reproduced on SVM. Unlike SVM, this version has 2 pending issues to resolve. 1. This seems to break 'vmx' kvm-unit-test in 'error code <-> (!URG || prot_mode) [+]' case. The test basically tries to do nested vm entry with unrestricted guest disabled, real mode, and for some reason that works without patch 2 of this series and it doesn't cause the #GP to be injected, but with this patch the test complains about unexpected #GP. I suspect that this test case is broken, but this has to be investigated. 2. L1 MTF injections are lost since kvm has no notion of them, this is TBD to be fixed. This was lightly tested on my nested migration test which no VMX sadly still crashes and burns on an (likely) unrelated issue.
