Using CoMA with VirtualBox #2

Open slambrechts opened 12 months ago

We followed the installation steps for using Using CoMA with VirtualBox at https://www2.uibk.ac.at/downloads/CoMA/CoMA_3.0_Manual.pdf, but when we try to start it to use it, we only get a black screen, so I guess it is not working. The log output is huge, but among the warnings and such I spotted the following message:

00:00:04.939584 CPUM: No hardware-virtualization capability detected

Is this what you hint at in the manual:

If you receive an error message similar to “VT-x/AMD-V hardware acceleration is not available
on your system”, you need to enable virtualization in the BIOS of your system

?

We checked wheter virtualization is enabled in the BIOS of our system, and it was, so we currently have no idea why it isn't working

Are you using Windows 10? There seems to be some issues with recent Win10 updates causing problems with VirtualBox.

Another possibility might be that another application is already using VT-x and hence blocks it for VirtualBox. This might be another VM platform, an anti-virus tool or Microsofts own Hyper-v VM application. Try to shut down all applications that might use virtualization. Open then the command line as admin and run "/set hypervisorlaunchtype off". Shut down your computer and anplug it for at least 10 seconds. Then start it again and enter your BIOS. Check wheter virtualization (e.g., VT-x) is enabled and also enable VT-D if available. Reboot the system and try to run CoMA on VirtualBox. I hope this helps!
