Deploying Mirantis OpenStack on a Single Citrix XenServer
Mirantis have recently published a Fuel Plugin for XenServer, allowing you to easily use the hypervisor deployed by the world’s largest cloud with OpenStack. The integration with Mirantis OpenStack makes the whole deployment straight forward – once the physical networking is defined.
The networking topology is often cited as one of the more complicated things to set up in OpenStack, particularly if you don’t have control over the switches or have a lengthy approval process with IT – ironically one of the things that IaaS solutions are intended to ease! This is where the power of Software Defined Networking (SDN) comes into play.
When using XenServer for your OpenStack cloud, the networking is fully abstracted from the Compute VMs and the instances. This means you can use XenServer to manipulate the network mapping between the physical devices and what OpenStack expects the networking to be. In fact, XenCenter, XenServer’s Windows GUI, allows you to create networks based on VLAN tags and to give them descriptive names and other metadata – but there is of course a lot more power available under the hood.
