<P> As of 2015, almost all newer server, desktop and mobile Intel processors support VT - x, with some of the Intel Atom processors as the primary exception . With some motherboards, users must enable Intel's VT - x feature in the BIOS setup before applications can make use of it . </P> <P> Intel started to include Extended Page Tables (EPT), a technology for page - table virtualization, since the Nehalem architecture, released in 2008 . In 2010, Westmere added support for launching the logical processor directly in real mode--a feature called "unrestricted guest", which requires EPT to work . </P> <P> Since the Haswell microarchitecture (announced in 2013), Intel started to include VMCS shadowing as a technology that accelerates nested virtualization of VMMs . 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 . As soon as more than one VMM or nested VMMs are used, a problem appears in a way similar to what required shadow page table management to be invented, as described above . In such cases, VMCS needs to be shadowed multiple times (in case of nesting) and partially implemented in software in case there is no hardware support by the processor . To make shadow VMCS handling more efficient, Intel implemented hardware support for VMCS shadowing . </P> <P> VIA Nano 3000 Series Processors and higher support VIA VT virtualization technology compatible with Intel VT . </P>
