[Xen-devel] May I comment out vmx_disable_intercept_for_msr()?

["K.C. Lee" <kcl.joseph@xxxxxxxxx>]

Hi,

I want to intercept the event of writing the address MSR_IA32_SYSENTER_EIP,

In xen 3.1.0, I can intercept the event in vmx_do_msr_write(),
In xen 4.0.1, I tried to intercept the event in vmx_msr_write_intercept(),
but I cannot intercept the event.

Later, I commented out vmx_disable_intercept_for_msr(v, MSR_IA32_SYSENTER_EIP) in construct_vmcs(),
and then I can intercept the event.

I want to know will it cause anything wrong to the hypervisor or guest or dom 0?
Is there any clever way to do this?


Any suggestion is appreciated,
greate thanks,

K.C.
