Of course, this all depends on the workload. For kernbench style benchmarks nested NPT probably gives you a bigger win, but anything doing IO is slowed down way more than it has to now.

What is causing 17K pio exits/sec?  What port numbers?

Any hints on how to easily find that out? For someone who's too stupid to get kvmtrace working :-).

You can always printk() every 1000 loops, but kvmtrace is actually pretty easy to use. Compile it in, run your guest (pinning to one cpu deconfuses the output), run kvmtrace -o blah, then use './kvmtrace_format formats' as a filter on the binary output.
