[PATCH] KVM test: Add new subtest iozone_windows
Following the new IOzone postprocessing changes, add a new KVM subtest iozone_windows, which takes advantage of the fact that there's a windows build for the test, so we can ship it on winutils.iso and run it, providing this way the ability to track IO performance for windows guests also. The new test imports the postprocessing library directly from iozone, so it can postprocess the results right after the benchmark is finished on the windows guest. I'll update winutils.iso on the download page soon.
