But I couldn't reproduce the results by simply applying the original patches to v3.6: - L2 Ubuntu 12.04 (64-bit) (smp 2) - L1 Ubuntu 12.04 (64-bit) KVM (smp 2) - L0 Ubuntu 12.04 (64-bit)-based. kernel/KVM is v3.6 + patches (the ones in nept-v2.tgz). https://bugzilla.kernel.org/attachment.cgi?id=93101 Without the patches, the L2 guest works. With it, it hangs at boot time (just black screen): - EPT was detected by L1 KVM. - UP L2 didn't help. - Looks like it's looping at EPT_walk_add_generic at the same address in L0. Will take a closer look. It would be helpful if the test configuration (e.g kernel/commit id used, L1/L2 guests) was documented as well. > I will have a use case for nEPT soon - testing purposes.
