Hello altogether!


Unfortunately, my machine won't run nor even fetch tasks other than camb_legacy. I'd really like to support by calculating camb_boinc2docker tasks.

Current state, specs:
- Oracle VM 6.1 is installed
- BOINC 7.16.7 is installed
- Hardware virtualization enabled in BIOS
- HyperV enabled in Windows 10 Version 1909 (soon to be 2004)
- Mainboard: MSI B450 GAMING PRO CARBON AC
- Video card: NVidia Geforce RTX 2070
- CPU AMD: Ryzen 7 2700X

What I tried:
- I enabled VT-x/AMD-v but I still don’t receive jobs
from FAQ (so deleting the line didn't work)
- Installing Docker and having it started (currently uninstalled)
- boinc2docker on Github (Don't know what to do with the files as I run no server; is it necessary to run one?)
- Pausing every other project
- and set C@H only to receive camb_boinc2docker or planck_param_sims (unticked camb_legacy)
- and updating the project regularly

Could it be that I have some other tasks unfinished from other projects and it won't fetch C@H tasks? I just deleted the line in the .xml few hours ago.

Any clues or tips?

I really do thank you in advance!

Edit:
Current projects and tasks here, if that might help:

Using BOINCStats/BAM and added (and detached for the FAQ thingy) C@H there.

Hyper-v and Virtual Box don't get along. You have to disable Hyper-V to run this project. Stick to non Virtual Box Boinc projects if you require Hyper-V on your machine.

Thanks!

Deactivated Hyper-V, halted other projects except C@H to let existing tasks finish and hopefully receive C@H after some days.
Still: No tasks.

Do I have to run and configure VirtualBox somehow?
It is installed, but as far as I know it runs automatically when a BOINC task needs it.

Could it be a problem that I often run Folding@Home in parallel?

It's fixed!

Went on ploughing through the forums. How it worked for me:

1. Limited CPUs (to 4, half of my physical 4; my Ryzen 7 2700X got 8 physical cores and 16 threads): https://www.cosmologyathome.org/faq.php#limit-cpu
Seemingly didn't do the trick after restarting, maybe just bad luck.

2. Uninstalled Sandboxie und Virtualbox 6.0.22
3. Reboot PC.

4. Installed VirtualBox 5.2.10 from here: https://www.virtualbox.org/wiki/Download_Old_Builds_5_2
(Got that tip from here: https://www.cosmologyathome.org/forum_thread.php?id=7563&postid=21913#21913)
5. Reboot PC.

7. In BOINC and the projects tab, selected C@H and clicked "Update". Finally received tasks camb_boinc2docker tasks!



Actually I'm not sure if step 1 is necessary. Maybe I'm gonna try delimiting. But right know, I'm just glad I can finally crunch.


EDIT:
After deleting the .xml, thus deactivating the CPU limit, it still worked :)

FYI, VirtualBox 6.0 and 5.2 versions are only supported until July 2020 per the Virtual Box website. It will still work afterwards but no more updates.
If you need to limit the number of cores over computers that aren't similar in number of true cores, use the app_config.xml method you linked. Set no new tasks. cancel pending tasks or let them finish. Create or edit your app_config.xml and then restart Boinc Manager. Allow new tasks. Any download tasks should now use the configuration along with the correct number of cores set. If you have computers with identical core counts, you can just set the cosmology at home preferences concerning number of tasks and max # CPUs.
