vboxsvc.exe AND vboxSDS.exe (Virtualbox Global Interface) shown in TaskManager.
Both have Version 6.1.34.636.
But, why vboxSDS.exe? Can this Task being deleted?

These "postponed" error tasks appear with all three applications using multi-attach VM's - ATLAS, CMS and Theory.

The last error task I had, was an interesting one https://lhcathomedev.cern.ch/lhcathome-dev/result.php?resultid=3101862

The difference to other tests:

- No other tasks running
- previous task (ATLAS) successful reported - No tasks in queue, but
- left VirtualBox GUI open waiting for new tasks.

I restarted testing of a pre-release vboxwrapper with multi-attach disks in the combination 1 dev-ATLAS (multi-attach) , 1 dev-Theory (multi-attach) and 1 production-Theory (normal).
The developer has made a minor change working around a VirtualBox error.
Somehow sometimes Vbox wrote VM-disk properties into a file where it was usual in old VBox versions.
That's why we got in our error tasks these strange message:
the media type 'MultiAttach' can only be attached to machines that were created with VirtualBox 4.0 or later
Tasks returned after 10:00 UTC today have used the newest pre-release.

ATLAS tasks of development
Theory tasks of development
Theory tasks of LHC@home production

Toby,
better here and not in production.
We had two days with problems in production, because of multiattach.
Crystal and the developer are on the right way.

Had saved this three CMS overnight.
After restart one got a Runtime-Error, the other two finished direct with no more task inside (10hours left).

Now two Theory with Theory_2020_05_08.vdi download are running (no postponed!)

One Atlas with Atlas_vbox_1.14_image.vdi download (Very slow download 474 KBps for this 1,09 GByte, dl now 1.670 KBps)

One Theory-Task from Production is also running.

Test with Threadripper (Atlas) get postponed. Atlas from Production is also running.
Is the Combination of Atlas from Production and Tasks from -dev (Atlas, CMS or Theory)
the postponed Problem?

Cannot attach medium 'C:\ProgramData\BOINC\projects\lhcathomedev.cern.ch_lhcathome-dev\Theory_2020_05_08.vdi': the media type 'MultiAttach' can only be attached to machines that were created with VirtualBox 4.0 or later.
Today seen. Is this change for Virtualbox-manager, or for vboxwrapper205?

... Is this change for Virtualbox-manager, or for vboxwrapper205?
The change has been made in the pre-release of vboxwrapper_26205.
I tested it 1.5 days in all kind of combinations: 2 ATLAS, 2 CMS with Theory, ATLAS with Theory.
I got (only) 1 error meaning the multi-attach wrapper still isn't 100% working around a VirtualBox-issue..
It's up to the admins whether this is acceptable.
In fact the wrapper is OK, but in my opinion the cause of the problem is in VirtualBox, sometimes writing to a file where it should not. The problem here is 'sometimes'.

Ok Crystal,
yes, the most important experience for Error's are for Windows from Virtualbox.
Testing atm new Boincmanager 7.20.2 in Combination with Virtualbox 6.1.36.
What seeing is: This Version installing Guest-Addition in the CentOS8-VM and CentOS9-VM correct.
You never get 100%, but if so less Error's you wrote, the Admin's of (Atlas, CMS and Theory) have to say us, what the next step.
Maybe, one Project after the other for Production.

Have the developer changed this Statement,
the media type 'MultiAttach' can only be attached to machines that were created with VirtualBox 4.0 or later?

Another Theory error task: https://lhcathomedev.cern.ch/lhcathome-dev/result.php?resultid=3101670

From BOINC's event log:
lhcathome-dev 25 Jul 20:17:45 Computation for task Theory_2390-1088592-272_0 finished
lhcathome-dev 25 Jul 20:17:45 Starting task Theory_2390-1104168-272_0
lhcathome-dev 25 Jul 20:19:01 Task Theory_2390-1104168-272_0 postponed for 86400 seconds: VM environment needs to be cleaned up.


Have the developer changed this Statement,
the media type 'MultiAttach' can only be attached to machines that were created with VirtualBox 4.0 or later?
Why do you think that?

Maybe I should have been more clear when I posted: "sometimes Vbox wrote "
I meant with VBox "Oracle VirtualBox" and not BOINC's vboxwrapper.
The message is still there in failed tasks.

Pre-release VBoxwrapper version 26205 is now released as the wrapper for CMS Simulation version 60.63

This version should have a successful workaround for the VirtualBox error writing a multi-attach HardDisk into the global virtualbox.xml.
