Thanks for the quick reponse to nightly status report. But we found that when in an extremely condition, like creating 12 VMX domains and 4 XENU domains at the same time, sometimes we still can meet this bug. Attached is a demo script to start many domains. So we just wonder changing the timout value could not resolve this issue completely. At the same time, we found when main_loop_wait is increased to 100 ms, windows guest's keyboard and mouse response is significantly slower. Ping
