1) Message boards : Number crunching : If you have used VirtualBox for BOINC and have had issues, please can you share these? (Message 68741) Posted 15 May 2023 by Purest Green Post: Issues with LHC tasks for very many days including a previous installation, but now resolved. Don't know if helpful but, since you ask the question - 2023-03-24: new motherboard (and hence new UEFI BIOS) LHC tasks e.g. ATLAS & Theory Simulation 300.07 persistently terminated after 17 to 20 seconds. Yeti's checklist was followed: BIOS amended to permit hardware virtualisation; Leomoon CPU-V confirmed hardware virtualisation was supported and enabled. LHC tasks persistently terminated as before... Hyper-V not enabled, Docker not installed Ryzen 7 3700X; 32GB RAM; 70GB free disc space + 43GB reported "available to BOINC" Windows 10 Pro v 22H2 BOINC Manager v. 7.16.11, wxWidgets version 3.0.1 VirtualBox 7.0.6 VirtualBox Extension Pack 7.0.6 installed 2023-04-13 (Note BOINC program and data are running on different drives.) No apparent anti-virus conflicts advised... but LHC tasks persistently terminated. Was unsure how to set the ports options advised in the checklist so took the 'nuclear' option of simple uninstall/reinstall of VB and BOINC; LHC Theory Simulation 300.07 tasks, confirmed to be using VB, are STILL RUNNING now after many minutes in (currently on VirtualBox v 6.1.12, no Extension Pack downloaded), though one task stated 'Ready to report' after just 15 mins, while others continued to run to various times including 1hr 29 mins. One now has an estimated remaining time of 9 days, but the basic termination fault seems now to have been remedied by the reinstall. Update: After the PC being turned off for 2 weeks and following a Windows update, the same fault recurred - that is cessation of LHC computing after a few seconds. Surprisingly, Leomoon CPU-V reported that hardware virtualisation was now NEITHER supported NOR enabled. BIOS settings showed that AMD-v was, in fact, still enabled. For reasons I cannot remember I changed Windows Security's Device Security's Core Isolation from Memory Integrity ON to OFF, which required a restart. Leomoon CPU-V confirmed hardware virtualisation was supported and enabled. LHC now runs. Experimentally, turned Core Isolation from Memory Integrity OFF to ON. LHC continues to run, so far for about 30 mins.
