I am using VirtualBox 6.x, I loaded up OVA file but it keeps showing a blank screen. What should I do?
DataStax Academy migrated to a new learning management system (LMS) in July 2020. We are also moving to a new Cassandra Certification process so there are changes to exam bookings, voucher system and issuing of certificates.
Check out the Academy FAQ pages for answers to your questions:
It sounds like your download is somehow corrupted. I've just downloaded it myself and it loads up in VirtualBox just fine.
Please download it and try again. Cheers!
UPDATE - I managed to track it down. This isn't an issue with the VM itself but the laptop or desktop where you're running VirtualBox, particularly on machines where it doesn't have a lot of CPU-processing power.
When you import the VM image, 3D acceleration is enabled by default:
Machines sometimes can't handle this correctly and end up displaying a blank screen. The workaround is to disable 3D acceleration in the settings (uncheck it in the "Display" tab):
This should stop VirtualBox from loading a black screen when you start the VM. Cheers!
