AMD virtualization (AMD-V)
AMD developed its first generation virtualization extensions under the code name "Pacifica", and initially published them as AMD Secure Virtual Machine (SVM),[20]but later marketed them under the trademark AMD Virtualization, abbreviated AMD-V.
On May 23, 2006, AMD released the Athlon 64 ("Orleans"), the Athlon 64 X2 ("Windsor") and the Athlon 64 FX ("Windsor") as the first AMD processors to support this technology.
AMD-V capability also features on the Athlon 64 and Athlon 64 X2 family of processors with "F" or "G" stepping on socket AM2, Turion 64 X2, and Opteron 2nd generation[21] and 3rd-generation,[22] Phenom and Phenom II processors. AMD-V is not supported by any Socket 939 processors. The only Sempron processors which support it are Huron and Sargas.
AMD Opteron CPUs beginning with the Barcelona line, and Phenom II CPUs, support a second generation hardware virtualization technology called Rapid Virtualization Indexing, later adopted by Intel as Extended Page Tables (EPT).

Linux: Find Out If CPU Support Intel VT and AMD-V Virtualization Support
Linux: Verify Intel VT CPU Virtualization Extensions
Type the following command as root to verify that host cpu has support for Intel VT technology, enter:
# grep --color vmx /proc/cpuinfo
Sample outputs:
Fig.01: Linux check Intel VT - if my server can run full virtualization or not
If the output has the vmx flags, then Intel CPU host is capable of running hardware virtualization.
Linux: Verify AMD V CPU Virtualization Extensions
Type the following command as root to verify that host cpu has support for AMD - V technology:
# grep --color svm /proc/cpuinfo
Again, the output has the svm flags, then AND CPU host is capable of running hardware virtualization.
Tip # 1: Check Your BIOS Settings
Many, system manufacturers disable AMD or Intel virtualization technology in the BIOS by default. You need to reboot the system and turn it in the BIOS.
Tip # 2: XEN Kernel
By default, if you booted into XEN kernel it will not display svm or vmx flag using the grep command. To see if it is enabled or not from xen, enter:
cat /sys/hypervisor/properties/capabilities
You must see hvm flags in the output. If not reboot the box and set Virtualization in the BIOS.
