Não sou o Rodrigo, mas lá vai:

The Second Generation: Virtualization-Ready Processors
The second major area of advancement came from Intel and AMD, the
major x86 processor makers. They began the process of implementing
extensions to the x86 architecture to make it more friendly to
virtualization. The concept of the first portion of their extensions
(known as "Intel Virtualization Technology" or "Intel VT" and "AMD
Virtualization" or "AMD-V" respectively) is to let the virtualization
engine tell the CPU when it is running in a virtualized context. The
virtualization engine also presents the CPU with a list of its
routines that can be called to support virtualization-unsafe
operations.

Fully-virtualized guests (HVM/Intel-VT/AMD-V)
To run fully virtualized guests in Xen or KVM, host CPU support is
needed. This is typically referred to as Intel VT, or AMD-V. To check
for Intel VT support look for the 'vmx' flag, or for AMD-V support
check for 'svm' flag
