long mode not supported usually means that VT-x/AMD-V is either not supported by your CPU or it is not enabled in your host BIOS.

The following topic gives you related information: FAQ: I have a 64bit host, but can't install 64bit guests.

The FAQ refers to the most common reason people encounter the problem, not the only reason. VT-x/AMD-v is also required e.g. if you add >1 vCPUs to a VM.
