Rapid Virtualization Indexing (RVI), known as Nested Page Tables (NPT) during its development, is an AMD second generation hardware-assisted virtualization technology for the processor memory management unit (MMU). [1] [2] RVI was introduced in the third generation of Opteron processors, code name Barcelona. [3]
Nested virtualization [56] (Intel processors only, both the host and guest instances of Hyper-V must be Windows Server 2016 or Windows 10 or later) Discrete Device Assignment (DDA), allowing direct pass-through of compatible PCI Express devices to guest Virtual Machines [ 57 ]
The nature of a nested guest virtual machine does not need to be homogeneous with its host virtual machine; for example, application virtualization can be deployed within a virtual machine created by using hardware virtualization. [22] Nested virtualization becomes more necessary as widespread operating systems gain built-in hypervisor ...
Dell will enable key features of the Windows Server 2012 virtualization platform for OpenStack, including network virtualization, policy-based isolation, Quality of Service (QoS) and multi-tenancy.
Full virtualization – Almost complete virtualization of the actual hardware to allow software environments, including a guest operating system and its apps, to run unmodified. Paravirtualization – The guest apps are executed in their own isolated domains, as if they are running on a separate system, but a hardware environment is not simulated.
Hyper-V (2012) Microsoft: x86-64 with Intel VT-x or AMD-V, ARMv8 [4] x86-64, (up to 64 physical CPUs), ARMv8 Windows 8, 8.1, 10, and Windows Server 2012 w/Hyper-V role, Microsoft Hyper-V Server Supported drivers for Windows NT, FreeBSD, Linux (SUSE 10, RHEL 6, CentOS 6) Proprietary. Component of various Windows editions. INTEGRITY: Green Hills ...
x86 virtualization is the use of hardware-assisted virtualization capabilities on an x86/x86-64 CPU. In the late 1990s x86 virtualization was achieved by complex software techniques, necessary to compensate for the processor's lack of hardware-assisted virtualization capabilities while attaining reasonable performance.
In computing, memory ballooning is a technique that is used to eliminate the need to overcommit host memory used by virtual machines (VMs) by letting each VM effectively "give back" unused pages of [virtual] memory.
