LHC@home

I've come back to LHC after a few years away.
Installed the version of Virtual Box that is packaged with BOINC version 7.16.20 and ran a few Rosetta tasks. They ran OK.
So I decided to head back to LHC knowing it needs VBox to run. Great, a couple of big files get downloaded and the first task ran for about 20 minutes before failing with exit code 194.
Second task does the same.
Looking through the log file I see this line:

Processor supports HW virtualization: no

Hold on, I'm running a Ryzen which supports some form of virtualisation. Reboot and see what the BIOS says...... hardware virtualisation was turned OFF. Turn it ON and see what happens.
The next few tasks run through and have validated.

Memo to self - Make sure hardware virtualisation is turned ON when trying to use VirtualBox.

Note to LHC - if you can show in the logs virtualization is off, don't download tasks that require it. Instead, give notice to the user that it is off. Possibly even direct them to resources on enabling it.
