You got 10 CMS-tasks and probably you started all 10 at once. Vbox don't like starting many machines in the same second.

Maybe the other 6 are still running. Hopefully they are running well.


Oh, thank you. Yes, other 6 runned correctly.
I'll keep an eye out

VirtualBox can't detect virtualization because it is in use by another hypervisor, in most cases Window's Hyper-V
=> Disable all Hyper-V components


Today i found that removing it from control panel/windows features seems not enough

Interesting meeting
From this paper

In development:
• Finish automatic retrieval and return of jobs
• Address credit issue by smart sampling of initial conditions
• Add enconding to protect against cheaters (currently only in conceptual phase)

• We need users! (not enough jobs - volunteers are eager to crunch)
