Three virtual MSRs added for guest to report the usage of software

Seems it's better like below. s/Three virtual MSRs added/Add three virtual MSRs ?

mitigations. They are enumerated in an architectural way. Try to access the three MSRs to ensure the behavior is expected: Specifically,

1. below three cases should cause #GP:

• access to a non-present MSR
• write to read-only MSRs
• toggling reserved bit of a writeable MSR

2. rdmsr/wrmsr in other cases should succeed

3. rdmsr should return the value last written
