i dont understand your question. but i think exec into vm has nothing to do with 'input connect 1025 using the io'. In other words, it has already exec into the vm?

@zmrush Sorry, maybe I was misunderstood. So what's the specific problem you got? What's the influence of blocking receiver? Please give more details.
