OVA Support for VMs

An Open Virtual Appliance (OVA) file is a tar archive file created by converting a virtual machine (VM) into an Open Virtualization Format (OVF) package for easy distribution and deployment. OVA helps you quickly create, move, or deploy VMs on different hypervisors.

Access to OVA operations is role-based. Based on your role, Prism Central helps you perform the following operations with OVAs:

  • Export an AHV VM as an OVA file.
  • Import OVAs of VMs or virtual appliances (vApp). You can import (upload) an OVA file with the QCOW2 or VMDK disk formats from a URL or the local machine.
  • Deploy OVA file as a VM.
  • Download an OVA file to your local machine.
  • Rename an OVA file.
  • Delete an OVA file.
  • Track or monitor the tasks associated with OVA operations in Tasks.


  • Layer 2 Traffic Isolation for Flow Isolation Policy -> With the layer 2 isolation feature, the capability to filter out layer 2 packets across isolated entities is added.
  • Policy Rule Description -> You can now add, edit, and view the description of each inbound and outbound policy rule of a target group in the Flow UI.
  • Services and Addresses for Policies -> Service and Address entities are introduced in the security policy configuration workflow. The ability to use the service and address entities in the policy creation workflow reduces any manual configuration error and enables reusability.
  • Enhanced Protection for VMs using External IPAM -> With enhanced protection for VMs that are using an External IPAM, Flow drops all packets to and from a VM protected by a policy in the apply mode by default.
