Hi, This patch series aims to add kvm-unit-tests for VMCS Shadowing emulation/virtualization feature added by KVM patch series: "KVM: nVMX: VMCS Shadowing emulation/virtualization". This patch series was developed by Jim Mattson and then cleaned-up and adjusted by myself to upstream kvm-unit-tests code. I consulted Jim and he suggested that I will submit the patches with myself as the Author and first Signed-off-by and him as the second Signed-off-by on all patches. Jim has also reviewed all the final patches submitted in this series. The specific tests added by this patch series is documented well in the commit message of patch 9 of this series. Regards, -Liran Alon
