Well, Virtualbox hadn't compiled, I was hitting https://www.virtualbox.org/ticket/1499.
Using a 32-bit kernel instead, I was able to get VirtualBox 4.3.32 to build. The results: # hardened, no sudo amnesia@amnesia:/media/amnesia/e3f702b9-64b4-40c2-96c3-ef6cf856e129/VirtualBox-4.3.32/out/linux.x86/release/bin$ ./VirtualBox VirtualBox: Error -10 in SUPR3HardenedMain! VirtualBox: Effective UID is not root (euid=1000 egid=1000 uid=1000 gid=1000) VirtualBox: Tip! It may help to reinstall VirtualBox. # hardened, as sudo: amnesia@amnesia:/media/amnesia/e3f702b9-64b4-40c2-96c3-ef6cf856e129/VirtualBox-4.3.32/out/linux.x86/release/bin$ sudo ./VirtualBox [sudo] password for amnesia: VirtualBox: supR3HardenedVerifyDir: Failed to open "/opt/VirtualBox": No such file or directory (2) # non-hardened, no sudo: Dialog Box: Kernel driver not accessible Failed to open a session for the virtual machine asdf.
