Re: [libvirt] [Discussion] How do we think about time out mechanism?

In fact, to deal with this kind of situation, we add some timeout codes in libvirtd, during remote_dispatch process. The mechanism is like this: 1. when we call an API, we start a thread to do the timer, when time out, the timer set a timeout flag to the API, and return timeout result to the libvirt client. 2. when the API return to remote_dispatch level, it checkout the timeout flag to consider what to do next. If timeout, we do some rollback action. It's like detach device, if we attach device at first. In this solution, there's something trouble, first, we have to figure out suitable rollback actions. Second, I'm not sure it's the best way to solve this kind of block problem, not so elegant. How do you think about it?
