Whoops.. so the hardware is reading the DS address as programmed by the host (host linear address) and using it as a guest linear address? Quality stuff.. Disabling PEBS events for guests isn't pretty though.. but I guess the only alternative is mapping the DS into the guest and reprogramming MSR_IA32_DS_AREA which is all a little involved I suppose? -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
