Linux kernel 3.10 or later with required dependencies. The following distributions have the required kernel, its dependencies, and are known to work well with Calico and OpenStack.
- RedHat Linux 7
- Ubuntu 16.04
- CentOS 7
Calico v3.3 requires a key/value store accessible by all Calico components. If you don’t already have an etcdv3 cluster to connect to, we provide instructions in the installation documentation.
Ensure that your hosts and firewalls allow the necessary traffic based on your configuration.
|Calico networking (BGP)||All||Bidirectional||TCP 179|
|Calico networking with IP-in-IP enabled (default)||All||Bidirectional||IP-in-IP, often represented by its protocol number
|All||etcd hosts||Incoming||Officially TCP 2379 but can vary|
* If your compute hosts connect directly and don’t use IP-in-IP, you don’t need to allow IP-in-IP traffic.
We aim to develop and maintain the Neutron driver for Calico (networking-calico) so that its master code works with OpenStack master or any previous release (back to Icehouse), on any operating system, independently of the deployment mechanism that is used to install it.
However, we recommend using OpenStack Newton or later, and our active support and testing of Calico v3.3 with OpenStack is limited to the following versions:
Tip: If you are using one of the recommended distributions, you will already satisfy these.

Nova patch needed with Mitaka and earlier
With OpenStack Mitaka and earlier, and if your libvirt is >= 1.3.3 and < 3.1, you will need to patch the Nova code post installation, on each compute host, as in this change. In case you need the same Nova code to work with all possible libvirt versions, you should then add this further change. OpenStack Newton and later already include these two changes.
