Intel Virtualization Technology (VT-
x) and AMD SVM Support
Intel VT-x Support
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 the
Intel site
http://www.intel.com/technology/computing/vptech/.
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
V
M Flags (page 108) 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
More Information (page 143) section of the About Parallels Workstation screen.
AMD SVM Support
Security and Virtual Machine (SVM) architecture, which is incorporated in the newest AMD
processors, provides enhancements implemented into processor architecture that are specially
designed for platforms running multiple operating systems. SVM 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 SVM see the
AMD site
http://enterprise.amd.com/us-en/Solutions/Consolidation/virtualization.aspx.
Security and Virtual Machine (SVM) architecture is fully supported by Parallels Workstation. If
Parallels Workstation detects a SVM-enabled CPU, support is automatically turned on. SVM
support can be manually enabled or disabled through a virtual machine configuration setting
available in the
VM Flags (page 108) section of General Options. If you run a guest OS with
SVM enabled, the
Virtualization mode flag in the About Parallels Workstation screen shows AMD
SVM
. See the More Information (page 143) section of the About Parallels Workstation screen.
