LHC@home

I have just installed Boinc on a new Fedora, installed everything for LHC and that seems fine, I then installed Vitualbox but Boinc is saying its not installed and wont download any units?

Under computers on this account its showing Virtualisation as non but its definatly enabled

lscpu | grep "Virtualization"
Virtualization: AMD-V

I did get an error regarding secure boot on install of Virtualbox, could this be the issue?, Virtualbox seems to fire up fine?

No I cant disable Secure Boot.

Ok I have tested with secure boot off and it works, any way I can get this working with Secure boot on?

No I cant disable Secure Boot.

Why can't you disable it?
Because of a technical reason (no, you wrote you already tested 'secure boot off'), a policy or anything else?

If it's due to a security policy, do you have explicit permission to run any software like BOINC or any app from an arbitrary project?

Assuming you are permitted, you would need to use certified software.
An example regarding VirtualBox can be found here:
https://askubuntu.com/questions/1455974/signing-virtualbox-modules-with-efi-secure-boot-enabled

The machine dual boots with Windows, a number of games require it.

I received the same message.
I wonder if BONIC is no longer supporting LHC@HOME, which uses it?

LHC@home requires BOINC as well as (most of it's apps) VirtualBox.
As you can see here there are lots of computers currently processing for LHC@home:

Your issue is most likely caused by Windows Hyper-V which doesn't forward hardware virtualisation to VirtualBox.
Hence, you may need to disable Hyper-V and everything that silently activates Hyper-V again, e.g. Secure Boot.

Additional hint:
Your stronger computer reports only 16 GB RAM.
This limits the #VMs it can run concurrently.
