I’d like to do something similar with Sys::Virt, but I can’t seem to wrap my head around its event system. The only examples I can find are the ones included in Sys::Virt source, which consist of a series of run_once() calls, or a while loop around run_default().</div><div style="font-family: Menlo-Regular;"><br></div><div style="font-family: Menlo-Regular;">Does anyone have any idea how I can make this play nicely with an existing event loop such as EV, or even to fire off ($cv->send) an AnyEvent condvar when the event I set in domain_event_register_any() triggers?</div><div style="font-family: Menlo-Regular;"><br></div><div style="font-family: Menlo-Regular;">Our current solution involves setting an AnyEvent->timer, which periodically fires off and then does a run_once() to see if any events happened during the period, but we’d like something more responsive (i.e., triggers when the event actually occurs) and less poll-y feeling.</div><div style="font-family: Menlo-Regular;"><br></div><div style="font-family: Menlo-Regular;">I’d appreciate any advice you may have—thanks!</div></div><div style="font-family: Menlo-Regular;"><br></div><div style="font-family: Menlo-Regular;">Scott</div></body></html>
