Hi John,
don't ask me why only strace shows the message (which is written to
stderr, so should be visible when you run VirtualBox by hand):
VirtualBox: Error -10 in SUPR3HardenedMain!
VirtualBox: Effective UID is not root (euid=1001 egid=50 uid=1001 gid=50)
VirtualBox: Tip! It may help to reinstall VirtualBox.
Error -10 is "access denied", and the next line complains that the
executable isn't installed as setuid root.
No idea which "make install" you're talking about... VirtualBox can't be
installed in such a way. Must be a VERY strange recipe you're following
(might have been applicable to some old 4.x builds, but certainly not to
anything recent).
BTW, what's that %U rubbish in the command line? Looks wrong to me
(smells like some desktop env parameter placeholder), but on the other
hand shouldn't do too much harm. I'd leave it out.
