When I try to create a 64bit linux guest on VirtualBox running on a CentOS 6.5 x86_64 host, I always get a GuruMeditation. I can confirm that VT-x is enabled in the bios, because when I disable it, I get the message from VirtualBox that it cannot run 64 bit guests without this. In the mean time, I've tried lots of different settings and different OS's, but nothing seems to work.
The host runs on an old Xeon processor. Maybe that could be a clue?
