What shall we do? |

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. |

Three CMS on this PC https://lhcathomedev.cern.ch/lhcathome-dev/results.php?hostid=3958 |

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 |

After this three CMS in the evening are finished, will testing your constellation also. But, with vboxwrapper204. |

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. |

A Theory task should try it 1 day later: https://lhcathomedev.cern.ch/lhcathome-dev/result.php?resultid=3101667 lhcathome-dev 25 Jul 18:45:24 Computation for task Theory_2390-1093114-272_0 finished lhcathome-dev 25 Jul 18:45:28 Requesting new tasks for CPU lhcathome-dev 25 Jul 18:45:31 Started download of 2390-1099200-272.run lhcathome-dev 25 Jul 18:45:32 Finished download of 2390-1099200-272.run lhcathome-dev 25 Jul 18:45:32 Starting task Theory_2390-1099200-272_0 lhcathome-dev 25 Jul 18:46:48 Task Theory_2390-1099200-272_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? |

Somehow sometimes Vbox wrote VM-disk properties into a file where it was usual in old VBox versions.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. |
