In fact I had taken a backup of the /var/lib/boinc-client directory after reinstalling the machine, I erased everything and reinstalled boinc-client and everything was back to normal.

Sorry for the inconvenience.

I installed virtualbox-6.1.34 on Debian 9.13 but Boinc-client returns me the message "VirtualBox is not installed" even though I reinstalled boinc-client!?

Hi,

I would like to change the priority of Vbox applications, I modified /etc/defaults/boinc-client to the values of:
BOINC_NICE_APP_DEFAULT = 19
BOINC_NICE_CLIENT = 10
to set them to 0 but that does not change after reloading boinc, I also put:
SCHEDULE = "0"
How to do ?

Posted 17 Feb 2021 by Sam Przyswa
Post:
Ok, and there is no way to find out why?

On your affected computers you may:
- shut down BOINC
- open "client_state.xml" in BOINC's data directory and check whether there's a line "<p_vm_extensions_disabled>1</p_vm_extensions_disabled>"
- if YES, remove that line and save the file
- start BOINC


Recent BOINC clients solve this automatically at every client restart but your client might be too old.


I upgraded to virtualbox v6.1.18, restarted Boinc, update project, it's ok now !

Thanks again.

11) Questions and Answers : Unix/Linux : Limited machine (Message 44334)
Posted 17 Feb 2021 by Sam Przyswa
Post:
... I have virtualbox installed ...

The BOINC client tests the hardware/BIOS for virtualization first.
If this test fails for whatever reason it doesn't matter whether VirtualBox is installed or not.


Ok, and there is no way to find out why?

2 of your computers show this entry on the computer details page:

https://lhcathome.cern.ch/lhcathome/show_host_detail.php?hostid=10680860
Virtualization None

Those computers will only be able to run SixTrack or ATLAS/Theory native which require a local CVMFS (already discussed).

To run VBox apps your computer must support virtualisation, it must be switched on and VirtualBox must be installed.

Ok but I have virtualbox installed as well as the necessary libraries on soleil-host:

14) Message boards : ATLAS application : ATLAS tasks are in calculation error (Message 44286)
Posted 8 Feb 2021 by Sam Przyswa
Post:
Unlike SixTrack ATLAS, Theory and CMS are very complex scientific apps that require access to large software repositories and DB snippets.
That data is distributed via CVMFS and Frontier.
To guarantee a well configured environment all of that is packed into a VirtualBox VM.

ATLAS/Theory native had bee developed later, mainly to save some RAM and - regarding CVMFS - to keep most of the files in a local cache.
So far native apps work only on Linux and a volunteer has to do more work to get them running.

If it's too much work or not compatible with your host system you may configure your computers to request only VBox apps:
https://lhcathome.cern.ch/lhcathome/prefs.php?subset=project


Thank you for all these explanations, I admire and respect all this work and it is a pleasure for me to participate in all these scientific projects and I thank you for all the work you do.

In fact I solved the problem I disabled the "Native" mode and now the ATLAS tasks are executed in Virtualbox I will revalidate the sending of the ATLAS tasks.

Hi,

When I registered on this project the ATLAS tasks were not causing problems with VirtualBox without having configured anything special, what is the interest of CVMFS?

For the moment I have changed my settings to no longer receive ATLAS tasks, thank you for your help anyway.

On Linux you can run ATLAS and Theory either as VBox app or as native app.
To run native apps a CVMFS client must be installed on the computer and it must be correctly configured.

There are a lot of comments about that in the forum.
Good starting points would be:

On Linux Ubuntu 20.04 since a few days all the ATLAS tasks are in calculation error, apparently VirtualBox does not launch. I restarted the whole project to see but it's still the same ...
