Instruction set extensions that have been added to the x86 instruction set in order to support hardware virtualization.These extensions provide instructions for entering and leaving a virtualized execution context and for loading virtual-machine control structures (VMCSs), which hold the state of the guest and host, along with fields which control processor behavior within the virtual machine.
The virtual machine control structure (VMCS) is a data structure in memory that exists exactly once per VM, while it is managed by the VMM. With every change of the execution context between different VMs, the VMCS is restored for the current VM, defining the state of the VM's virtual processor. [ 31 ]
Oracle VM Server for x86 is a server virtualization offering from Oracle Corporation. Oracle VM Server for x86 incorporates the free and open-source Xen hypervisor technology, supports Windows , Linux , and Solaris [ 3 ] guests and includes an integrated Web based management console.
In computing, a virtual machine (VM) is the virtualization or emulation of a computer system. Virtual machines are based on computer architectures and provide the functionality of a physical computer. Their implementations may involve specialized hardware, software, or a combination of the two.
LinuxCNC (formerly Enhanced Machine Controller or EMC2) is a free, open-source Linux software system that implements computer numerical control (CNC) capability using general purpose computers to control CNC machines. It's mainly intended to run on PC AMD x86-64 systems.
When processes use virtual addresses and an instruction requests access to memory, the processor translates the virtual address to a physical address using a page table or translation lookaside buffer (TLB). When running a virtual system, it has allocated virtual memory of the host system that serves as a physical memory for the guest system ...

Moves to the CR3 control register are serializing and will flush the TLB. [l] On Pentium and later processors, moves to the CR0 and CR4 control registers are also serializing. [m] MOV reg,DRx: 0F 21 /r [j] Move from x86 debug register to general register. [k] MOV DRx,reg: 0F 23 /r [j] Move from general register to x86 debug register. [k]
