This section describes the software requirements for OpenStack cloud.

For details on supported software version, see Software Requirements for OpenStack Cloud section.

The Avi Load Balancer image is available in qcow2 (QEMU Copy ON Write) format or raw image of the Controller and SEs. The SE software is embedded in the Controller image and does not require separate installation. In case of OpenStack generic cloud (with Avi Load Balancer Cloud Connector), the Controller pushes qcow2 image for SE towards OpenStack Glance. In case of a no-access cloud, you need to download the qcow2 image for SE and then manually upload to OpenStack Glance.

Note:

In KVM/ OpenStack, the Service Engines have a limitation of 24. To support 24 vNICs, Service Engines must be configured with at least 3 GB of memory.
