Virtual Machines
A virtual machine (VM) is a software implementation of a computing environment in which an operating system (OS) or program can be installed and run. The VM typically emulates a physical computing environment, but requests for CPU, memory, hard disk, network and other hardware resources are managed by a virtualization layer which translates these requests to the underlying physical hardware.
You can deploy an Open Virtualization Archive (OVA) file. The OVA file package simplifies the process of deploying a VM by providing a complete definition of the parameters and resource allocation requirements for the new VM.
An OVA file consists of a descriptor (.ovf) file, a storage (.vmdk) file and a manifest (.mf) file.

You can also install the Cisco CSR 1000V using an .iso file and manually create the VM in the hypervisor.
For more information, see the “Cisco CSR 1000V Series Cloud Services Router Overview” section on page
Hypervisor Support
A hypervisor enables multiple operating systems to share a single hardware host machine. While each operating system appears to have the dedicated use of the host's processor, memory, and other resources; the hypervisor controls and allocates only needed resources to each operating system and ensures that the operating systems (VMs) do not disrupt each other.
The Cisco CSR 1000V is supported for installation on selected hypervisors. The following table lists the supported hypervisor versions for your software release.
Note Beginning with Cisco IOS XE Release 3.11S, the Cisco CSR 1000V can also be deployed on Cisco Amazon Web Services. For more information, see the Cisco CSR 1000V Series Cloud Services Router Deployment Guide for Amazon Web Services.
