Intel Virtualization Technology (VT-x), which is incorporated in the newest Intel processors, provides enhancements implemented into processor architecture that are specially designed for platforms running multiple operating systems. VT-enabled processors facilitate more efficient Virtual Machine partitioning and more precise virtual processor simulation. An extended set of processor instructions performs on a hardware level tasks previously realized programmatically, thus reducing virtualization overhead and improving Virtual Machine performance, security and stability. To learn more about Virtualization Technology see Intel site.
Intel Virtualization Technology is fully supported by Parallels Workstation. If Parallels Workstation detects a VT-enabled CPU, support is automatically turned on. VT-x support can be manually enabled or disabled through a Virtual Machine configuration setting available in the VM Flags section of General Options. If you run a guest OS with VT-x enabled, the Virtualization mode flag in the About Parallels Workstation screen shows Intel VT-x. See the Additional Information section of the About Parallels Workstation screen.
