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]
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]
In fact, an entire Operating System (OS), along with the applications running within, can be run in a virtual machine (VM). However, when multiple VMs concurrently run on the same physical host, they share the available physical resources, including CPU(s), network adapter(s), disk(s) and memory. This adds a level of unpredictability in the ...
In other words, nested virtualization refers to running one or more hypervisors inside another hypervisor. 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.

Azure Virtual Desktop with Windows 10/11 Enterprise Multi-Session is a cloud-based alternative to an on-premise Remote Desktop Server (RDS). AVD is deployed in Azure Cloud as a virtual machine. License costs are already included in several Microsoft 365 subscriptions, including Microsoft 365 Business Premium or Microsoft 365 E3.

Live migration, also called migration, refers to the process of moving a running virtual machine (VM) or application between different physical machines without disconnecting the client or application. Memory, storage, and network connectivity of the virtual machine are transferred from the original guest machine to the destination.
The virtual or physical functions available to the hypervisor or guest operating system depend on the PCIe device. [3] The SR-IOV allows different virtual machines (VMs) in a virtual environment to share a single PCI Express hardware interface. In contrast, MR-IOV allows I/O PCI Express to share resources among different VMs on different ...
