Can you give an example? > Sorry. No concrete example for now. We are developing this on a conservative policy and I have put the vmcs processing in a new module in patch set v2 as you required. The new module is auto-loaded when the vmx cpufeature is detected and it depends on module kvm-intel. Loading and unloading this module will have no side effect on the running guests. And one thing I have to stress is that, we can see guest image as crash dump from guest machine's view if we have the vmcsinfo, this itself is useful. Thanks Zhang Yanfei
