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.
• ovf file—Descriptor file which is an xml file with extension .ovf which consists of all the metadata about
the package. It encodes all the product details, virtual hardware requirements and licensing.
• vmdk file—File format that encodes a single virtual disk from a VM.
• mf file—Optional file that stores the SHA key generated during packaging.
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 “Installation Overview” section on page 3-1 .
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.
Supported Hypervisor Types
Installation of the Cisco CSR 1000v is supported on selected Type 1 (native, bare metal) hypervisors.
Installation is not supported on Type 2 (hosted) hypervisors, such as VMware Fusion, VMware Player, or
Virtual Box.
Amazon Cloud Marketplace
The Cisco CSR 1000v is available in the Amazon Cloud Marketplace. (For use with Cisco IOS XE Release
3.11S through 3.16.2S, and Cisco IOS XE Denali 16.3.1 and later.) For more information, see the Cisco CSR
1000V Series Cloud Services Router Deployment Guide for Amazon Web Services.
Microsoft Azure Marketplace
The Cisco CSR 1000v is available in the Microsoft Azure Marketplace . For more information, see the Cisco
CSR 1000V Series Cloud Services Router Deployment Guide for Microsoft Azure .
