UPDATE

   What is TCG? If your server CPU does not support virtualization extension, then it is the job of the emulator (or hypervisor) to execute the Virtual CPU instruction using translation. QEMU uses TCG or Tiny Code Generator to optimally translate and execute the Virtual CPU instructions on the physical CPU.

However, check BIOS settings you might have VT-X disabled.
