Virtual Services Container

Virtual Services Container

Prerequisites for a Virtual Services Container

  • You must have a Cisco device installed with an operating system release that supports virtual services and has the needed system infrastructure required for specific applications like Cisco Plug-in for OpenFlow.


    Note

    A compatibility matrix is delivered with each Cisco application. Refer to this matrix for information about which operating system release supports the features and infrastructure necessary for a particular application such as Cisco Plug-in for OpenFlow.

  • You must download an open virtual application (OVA) package that is compatible with the device operating system, and downloaded from an FTP server connected to the device.

  • You must have enough memory for installation and deployment of application. Refer to the application configuration guide for specific recommendations.

Information About Virtual Services Container

Virtual Services Containers and Applications

A virtual services container is a virtualized environment on a device. It is also referred to as a virtual machine (VM), virtual service, or container.

You can install an application within a virtual services container. The application runs in the virtual services container of the operating system of a device. The application is delivered as an open virtual application (OVA), which is a tar file with a .ova extension. The OVA package is installed and enabled on a device through the device CLI.

Cisco Plug-in for OpenFlow is an example of an application that can be deployed within a virtual services container.

Some of the files that can be found in an OVA file are the following:

  • Virtual machine definition file, in libvirt XML format, with Cisco extensions.

  • Manifest file, listing the contents of a distribution. It contains the hash information for each file in the OVA package.

  • Certificate file containing the signature of a manifest file. This file is used in validating the integrity of an OVA package.

  • Version file, used to check compatibility with the virtualization infrastructure.

oneFW                   Activated          iosxe-cx-9.0.2-hudson...
            Possible Cause    Deactivation takes a long time (5 minutes).
            Solution    Check if application directories are in use. Ensure that there are no shells open in the application file system directories on the device.
            Possible Cause    The application does not deactivate gracefully due to unknown reasons.
            Solution    As a last resort, uninstall the application (if you haven't done so yet) and delete the virtual-instance.conf configuration file, using the delete command and reload the device. This step deletes all applications installed in the virtual services container. 
            Device#  delete bootflash:virtual-instance.conf
Device#  reload
            Solution    If the problem persists, generate general troubleshooting information and contact Cisco Technical support. For more information, see Collecting General Troubleshooting Information.
