Actually I saw this "lost interrupts" spew on the host (ie the non-virtualized kernel) running just plain qemu (no kvm or anything scary like that). It seemed to be some long irqs-off latency in the tun/tap or bridging code (it went away when I stopped using "-net tap" on the qemu command line), but I never succeeded in getting Ingo's latency tracer to be able to track it down. - R. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
