vboxheadless.exe is running several instances even when I have Boinc Manager and the Boinc Service stopped

I'm in the process of trying to determine which project(s) is running

Anyone have any ideas why this might be happening?

Thanks

It happens to me too.
At least in Ubuntu 14.04.
I have to enter the VM Manager manually and click "pause" in the machines that are still running.

For both, this is really something you'll have to tell the affected project(s) first, as then they can check if it's something their application does, or the BOINC wrapper. And if the latter, they'll be able to report that to the BOINC developers.

Without even a hint of which project(s) application(s) that's doing this, it's very difficult to make a guess.

VLHC, Atlas, both do this. There seems to be an issue between BOINC and the VM. BOINC is unable to command the VM itself to pause, because, well, it is a VM! However it can send a kill request, so as a work around, tell BOINC not to leave suspended tasks in memory. This way BOINC should send a kill to the VM after the pause and the VM will quit. (I believe the task running in the VM properly pauses if left in memory, but the VM overhead continues. I don't believe the VM itself has a pause option.)

I know there was a lot of chatter when VM's first came under BOINC that they were "stealing cycles" when they should not have been running. So this may be more of a documentation issue than something that can be fixed short of writing an entire VM.
