These patches are intended to allow the svm tests to run on bare-metal. The second patch indicates there is a bug in KVM. Unfortunately, two tests still fail on bare-metal for reasons that I could not figure out, with my somewhat limited SVM knowledge. The first failure is "direct NMI while running guest". For some reason the NMI is not delivered. Note that "direct NMI + hlt" and others pass. The second is npt_rw_pfwalk_check. Even after the relevant fixes, exit_info_2 has a mismatch, when the expected value (of the faulting guest physical address) is 0x641000 and the actual is 0x641208. It might be related to the fact that the physical server has more memory, but I could not reproduce it on a VM with more physical memory.
