Your processor looks like it does support VT-x, although running the tools found on that other page still might not hurt, they may at least give you other error messages to look into. You can try these, but honestly I don’t expect then to report anything abnormal

The other possibility is that it could be turned off in your BIOS. Here’s two links, the first describes how to enable virtualization in your BIOS, the second is just an example of what to look for.
Verify that and if you’re still having problems come back here.
