Adding a KVM profiler to autotest
Create a profiler to bracket test run(s) by loading and unloading the
kvm and kvm_intel or kvm_amd kernel modules. Allows comparison
of other test runs with and without the KVM modules loaded.
Add return codes to the kvm_control utility functions to detect nonzero
return values for modprobe / rmmod.
See http://www.linux-kvm.org/ for description of kernel-assisted VMs.
Motivation: improve coverage for the kernel virtual machine support code.
Risk factor: low, an optional new profiler.
