Development for LHC@home

All my tasks end up with the message:

21.03.2015 10:56:07 | CMS-dev | task postponed 86400.000000 sec: VM Hypervisor failed to enter an online state in a timely fashion.

and in the VB Manager it is written that the task has been canceled.

My System is Win 7 and VB 4.3.26.

hat can I do?

The wrapper had to wait too long for communication due to VBox Service too busy/not responding.
BOINC waits for a (very) long time and try again.
To avoid that long waiting period, the only thing you can do is restarting BOINC.

BUT, meanwhile CMS is using the newest vboxwrapper v26156 and it could be that this is solved or at least resolved in an other way.

Your current task is using this new wrapper.

As far as I can see, these happen if the system is shut down for a while.
For some reason, the wrapper fails to restart the VM.

See http://boincai05.cern.ch/CMS-dev/forum_thread.php?id=41&postid=306#306; I'm having the same problem. And, I am not shutting down my machines. They are running pretty much 24/7.

I too have noticed this message: 5/10/2015 11:28:19 AM | CMS-dev | task postponed 86400.000000 sec: VM Hypervisor failed to enter an online state in a timely fashion.

My Computer has not been turned off. Other works units are running with no problem. I am aborting this work unit as it has not run on the system in over 24 hours yet other work units finished and started new work units while this remained in the postponed status.
