There are a few comments recently about whether VirtualBox 5.2 works or not with ATLAS. According to Laurence the BOINC community suggests 5.2.16 is a good version. Please let us know if you have issues with this version.

Personally the 5.2.16 gives many unmanageable errors with ATLAS. The CMS, LHCb, Theory have no issues.

The 5.1.38 works well for all tasks.

I don't think others have computers that can run so many WU at once?

I have started to upgrade machines (Win10 1803) to VB 5.2.16 and BOINC 7.12.1 and until now, this works fine. So far I haven't seen any unmanageable errors, Maybe it has something to do with my clients that are never allowed to use more than 75% of CPU-Power

Did you upgrade BOINC too ?


Supporting BOINC, a great concept !

Machine is running Windows 10 - 1803, VB 5.2.16 and BOINC 7.12.1.

Tried running a 3-core ATLAS, 2-core Theory, and a 1-core LHCb tasks at the same time.

The Stderr.txt for the ATLAS task had the following error message:
2018-08-09 12:57:11 (1988): Error creating VirtualBox instance! rc = 0x80004002

While the tasks were processing, the machine stopped running. When I restarted it, the Event Log had this message:

8/9/2018 3:41:13 PM | LHC@home | [error] no project URL in task state file

Atlas task finished and validated, Theory and LHCb tasks are still running.

Let me know if you need more information.

Have upgraded Virtualbox from 5.2.8 to 5.2.16. Windows 10 pro (10.00.16299.00).
Atlas-Task with Boinc 7.12.1 get Status unmanagable!
After changing the priority from vboxsvc.exe from "normal" to "lower than normal" it is running.

Today in the morning I upgraded a Win7 Client in the middle of two Atlas-WUs to BOINC 7.12.1 and VirtualBox 5.2.16.

The WUs have finished normal, have their HITs-File and got validated.

Until now I have crunched 100 WUs with 5.2.16 and there was no problem so far

Yes, I did both, I allow 100% of CPU usage so it's likely to do with that?

Maybe, so far I had not any unmanagable VM.

And I had to downgrade several installations of BOINC to 7.8.3, not regarding ATLAS, but because of problems with the Grafic-Card not running in additional Instances of BOINC, but VB 5.2.16 is still running fine

If you're looking for the latest VirtualBox 5.2 packages, see VirtualBox 5.2 builds. Please also use version 5.2 if you still need support for 32-bit hosts, as this has been discontinued in 6.0. Version 5.2 will remain supported until July 2020
