Hi Tyler,

I have a question for below code.

On 2017/3/25 0:01, Christoffer Dall wrote:

when it is SEA synchronized abort, why here inject a asynchronous abort through kvm_inject_vabt(vcpu) instead of synchronized abort? seem the original kvm source code is also do that, so I am confused about that.
thanks .
