[ port from runtime commit 0100af18a2afdd6dfcc95129ec6237ba4915b3e5 ]
To control whether guest can enable/disable some CPU features. E.g. pmu=off,
vmx=off. As discussed in the thread [1], the best approach is to let users
specify them. How about adding a new option in the configuration file.
Currently this patch only supports this option in qemu,no other vmm.
