How to check if CPU supports hardware virtualization (VT technology)
To run KVM, you need a processor that supports virtualization. For Intel processors this extension has name INTEL-VT, for AMD processors it has name AMD-V.
To see if your processor supports one of these technologies, please run the following command under Linux:
# egrep ‘(vmx|svm)’ /proc/cpuinfo
If nothing is printed, it means that your CPU does not support hardware virtualization. Otherwise, it does – but you still need to make sure that virtualization is enabled in the BIOS. If the svm flag is returned then your processor supports AMD-V or if the vmx flag is returned then your processor supports Intel VT.
