Hence, you may need to completely remove VirtualBox before you install it again (most recent version is recommended).


Great idea. I upgrade VirtualBox 7.1.4 to 7.1.6 (on the second pc) and now no machine starts. Error "NtCreateFile(\Device\VBoxDrvStub)"
Remove all, reinstall all, launch VBoxDrv.inf install, same error.
Well done, Oracle guys

No.


Well, yes.
Cpu supports virtualization? Yes
Is virtualization enabled? Yes (both Windows Manager and Bios configuration are correct)
Hyper-V is installed? No
Are virtual machines running correctly on the pc? Yes

So, if is not an error of lhc site, whose fault is it?

After removal and before a fresh installation you should also remove the directory "C:\Users\<your_user_name>\.VirtualBox\" to allow VirtualBox to create a fresh profile.


I'll try to return to 7.x version.

vboxwrapper is difficult, because of Theory, CMS AND Atlas in Windows.

Registry key "Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\DeviceGuard\Scenarios\WindowsHello\Enable"? Does not exist

If the key does not exist, create it and set it's value to "0"?

Create a new registry key to download some wus? It seems not a good idea...

In addition ensure "Run native if available? (Not recommended for Windows)" at the prefs page is not checked for the venue your Windows computers are attached to.

I have Windows and this option has never been enabled.

Cpu virtualization? Enabled

App_config.xml? Not present

I run correctly some virtual machines (win and linux) on my VirtualBox 7.1.4, despite lhc@home continues to say that my "cpu does not support virtualization"

web and scheduler: enable plan classes for BUDA

If you make a variant of a BUDA app for a plan class
(e.g. NVIDIA GPU with CUDA)
this ensures that jobs submitted to that variant are sent
only to capable hosts,
and that the host usage and projected FLOPS are set correctly.

On the web side, we add a <plan_class> element to workunit.xml_doc.
This gets sent to the scheduler.

On the scheduler this required some reorganization.
As the scheduler scans jobs, it finds and caches
a BEST_APP_VERSION for each app.
This contains a HOST_USAGE.

In the case of BUDA, the host usage depends on the workunit,
not the app version.
We might scan several BUDA jobs
they'll all use the same APP_VERSION,
but they could have different plan classes
and therefore different HOST_USAGE.

Simulation of heavy ions ended.

The integrated luminosity of the proton run, which denotes the number of collisions recorded, reached almost double the best performance achieved in previous runs, with124 inverse femtobarns for both the @atlasexperiment and the @cmsexperiment. Later, during the 17-day lead-ion run, an integrated luminosity of 1.98 inverse nanobarns was delivered to the @alice_experiment, an equivalent amount to last year.

Particles are set to return to the accelerator chain at the beginning of March 2025 and to the LHC at the beginning of April.
