Looking at the specs for the processor it does not seem to have the vmx features in /proc/cpuinfo:
http://www.notebookcheck.net/Intel-Core-2-Duo-T6400-Notebook-Processor.35100...
and the output from grep -E ‘vmx|svm’ /proc/cpuinfo is empty.
Hello,
IMO, it's better to check for this on the official Intel site: http://ark.intel.com/products/40479/Intel-Core2-Duo-Processor-T6400-2M-Cache...
This CPU does not support hardware-assisted virtualization.
