What is vmx 1?

VMX 1 typically refers to Virtual Machine extensions, which are a set of instructions that are incorporated in Intel and AMD processors to facilitate virtualization. These extensions provide hardware support for virtualization and help to create a separate platform for running multiple virtual machines on the same physical server.

VMX 1 was introduced in 2005 with Intel's first generation of virtualization-enabled processors. It supports both 32-bit and 64-bit guest operating systems and provides support for hardware-enhanced memory management, IO virtualization, and CPU virtualization. This enables virtualized environments to deliver better performance and security while reducing the overhead associated with traditional virtualization techniques.

Today, most modern processors incorporate VMX extensions, with newer versions of the extensions being released regularly to address emerging virtualization needs and to support new features in hypervisors and guest operating systems.
