Posted 23 Feb 2025 by nairb Post: [quote]Your computer details show this: Virtualization None In kernel 6.12, KVM initializes virtualization on module loading by default. This prevents VirtualBox VMs from starting. In order to avoid this, either add "kvm.enable_virt_at_load=0" parameter into kernel command line or unload corresponding kvm_XXX module /quote] Thanks computezrml, its been ages since I had to sort out fc36 and had forgotten much. The groups were fine The lsmod |grep -i vbox showed nothing. Sorting thru the vbox logs showed that it had failed to set up the virtual box. In particular there was a lib or header file missing. So I did a sudo dnf install kernel-devel kernel-devel-6.11.4-301.fc41.x86_64 which gave the missing info. Followed by a /sbin/vboxconfig to rebuild the thing. That solved the first problem. The second one was the KVM problem.......(new to me) Solved by using/adding the blacklist.conf file in /etc/modprobe.d A couple of lines blacklist kvm blacklist kvm-intel So its switched off even after a re-start. So vbox now works on fedora 41 lxde and 41 workstation with the dreaded gnome desktop and the much more useful 41 KDE. The lxde desktop is ideal for Boinc work and small capacity hard disks. Thanks for your help |

(Message 51579)
Posted 20 Feb 2025 by nairb Post: I have virtualbox installed on fedora 32 and 36. And on 36 lxde (I think). They are working fine. So I decide to try out the latest version of fedora 41 and 41 lxde. I installed virtual box like before(I assume) and sudo dnf boinc_client boincmgr. Boinc now works fine with projects that don't use virtual box, but I get the dreaded...... "Message from server. "Virtual box not installed" . Virtual box has installed ok i think. Virtualization is on in the bios. This machine runs fedora 32/36 fine. Dont suppose anybody else has tried fedora 41 and managed to get vbox working Ta Nairb |

Posted 16 May 2024 by nairb Post: One of the w/u is using 4 cpu's and 1850 events and shows 4 worker progress lines on an alt-F2. Another w/u is using 4 cpu's and shows 400 events and only 1 worker progress line. I seen NO athena.py process on an alt-F3. And N/A for most of the information on the alt-F2 Is this correct.... I might have aborted a couple of tasks thinking this is wrong for the 400 task jobs Ta Nairb |

Fedora 36 runs atlas w/u OK. ALL CMS fail
(Message 47979)
Posted 6 Apr 2023 by nairb Post: Many thanks for the info. I followed your instructions and now the machine is running 2 cms jobs fine. It's only using half the available ram, so might even be able to run 3 jobs at once, I have set the preferences to have only 2 jobs at once to be sure. All is now running fine Ta Nairb |

(Message 47973)
Posted 5 Apr 2023 by nairb Post: A fedora 36 machine will run ATLAS jobs fine. But sofar all CMS jobs fail with "00:00:05.652853 Console: VM runtime error: fatal=false, errorID=VMBootFail message="The VM failed to boot. This is possibly caused by not having an operating system installed or a misconfigured boot order. Maybe picking a guest OS install DVD will resolve the situation". VBox works well with Atlas but not with CMS. Vbox ver 7.06. Any clues?? other than dont run cms. Ta Nairb |

Questions and Answers :
Unix/Linux :
Installing vbox on fedora30
(Message 46849)
Posted 6 Jun 2022 by nairb Post: For those who worry about such things I have managed to install vbox on fedora 36. Not the best solution. So I tried one of the fedora spins the LXDE one. It requires much less disk space which is great since I have a bunch of sata 40g disks. It took a fair amount of effort to get boinc to see virtualbox. A good many messages saying that vbox was not installed. Anyway after a few hours it was fixed. SO fedora 36 and vbox seem to be a winning combination. |

Posted 1 Jun 2022 by nairb Post: Well, for what it's worth...... I have a disk with fedora 32 installed. So I plugged it into a 4core I5 machine. And after a fair bit of effort managed to get vbox 6.1 installed as well. I set the application to use only 2 cpu's at once and set it off. Well sofar it's doing ok. So it looks like fedora 32 is ok to use. I know it's not a mass market, but I suspect fedora 33/34 will be ok as well. |

Installing vbox on fedora30
(Message 46699)
Posted 28 Apr 2022 by nairb Post: Well the Orale/VirtualBox website says fedora 32 or fedora 33/34/35. So it looks like I dont have the kit to run this atlas stuff. I dont want to upgrade to the latest fedora because I dont know if I could get the libs for CPDN. I think fedora dropped 32bit support after fedora 30. This windoze laptop just does not have the memory to run atlas and other tasks together. There is always sixtrack. Ta Nairb |

Posted 26 Apr 2022 by nairb Post: Hurrrray its done an Atlas w/u and its been Completed and validated. The smart move now is to let it complete the w/u left and set up the desktop with vbox and run Atlas from there since its always connected to the internet. This laptop is better with the six track w/u. But at least its worked for once. Ta Nairb |

Low cpu usage
(Message 46678)
Posted 25 Apr 2022 by nairb Post: Yes that was the real problem - not enough memory. I followed the checklist but still needed to stop a couple of other processes to get enough memory for the vbox to work. Even the F2/F3 keys work now. I get 2 athema.py processes running and it has completed 10 of 200 events so far. Its plain I will have to increase the amount of memory on this machine if I want to run atlas on a regular basis. Thanks to all who have helped. I would have probably given up otherwise. I will try getting the I7 machine set-up with vbox but had better wait till the cpdn jobs have finished first. Thanks Nairb |

Low cpu usage
(Message 46676)
Posted 24 Apr 2022 by nairb Post: Right I have a major step forward. For some reason the alt f3/f2 gave the login prompt (again) but this time I used atlas login (again) and for the first time ever I was logged in. Hurray. Now I am more familiar with linux so first i found out that it does see 4 cpus. Top produced some interesting info. A quick grep with athena and nothing was found. All cpu's are idle. The id in top is 99.9%. Nearly all memory is free. So it would seem that nothing is being processed. There are 4 cpu's in the top list. Is there a log somewhere that might show why its failed or not processing? or failed to start. Ta Nairb |

Low cpu usage

Posted 24 Apr 2022 by nairb Post: So, in the VirtualBox manager I press the green "show" icon. I get a black window which I can try and log on. If I select "machine from the menu and then session information from the drop down menu I get another screen showing cpu load at about 50% average. But I dont know if that is all four cpu's or just 1. From Boinc if I select properties from the running job is says 7.30mins of cpu time and 4 seconds CPU time since checkpoint. With an Elapsed time of 18.36 hrs. I think I have opened all the correct port numbers. I dont think this is working. And I dont think it ever has on this win10 machine for some reason. I ran the V-CPU from LeoMoon and have 2 green boxes. I bet if I leave this running it would take 3+ days if it dosen't fail first |

Posted 23 Apr 2022 by nairb Post: Thanks for the info. Its running all 4 cpu's and still at about 60%. Its been running nearly 24hrs and its at 79%. Somewhat longer than the 15 hrs stated in boinc. It looks like running another 12 hrs at least. Still all normal?? Ta Nairb |

Posted 22 Apr 2022 by nairb Post: Just added ATLAS Simulation. Downloaded the latest version of VM box 6.1 and downloaded a few Atlas jobs. I suspended all but 1 job and its started and "seems" to be running?. It is doing about 6.5%/hr. I notice that the cpu load is averaging about 60%. Is this normal?. All other other jobs from other projects seem to run 100%. Even the six track runs max speed. The normal windoz task manager show very little cpu load. Is this all normal? Ta Nairb |
