Cisco Nexus 1000v virtual switch extension for Microsoft Hyper-V 3 Beta

Exciting times for anyone in the Hyper-V camp or those looking. For a long time VMware has led the way with a extensible networking system whereby 3rd parties can connect their technology with the Hypervisor. I won’t doubt that Microsoft was envious of such enthusiasm by vendors and customers alike with this feature. One of the prominent vendor extensions is Cisco’s Nexus 1000v virtual switch.

Essentially you get all the power, flexibility and networking expertise of the Cisco Nexus switch line (including the NX-OS operating system) in a virtual package. This is especially useful in an environment that is already dominated by physical Cisco switch environment (which would be a vast majority of big organisations and datacentres alike) as it means a unified environment and your networking team can continue to control ALL of the network in your environment instead of just the physical switching/routing environment. In essence, less retraining and more getting things done!

Which brings me back to the reason for this blog. Cisco have honoured their word and have brought the 1000v to Hyper-V 3 (the version of Hyper-V shipped with Windows Server 2012 and Windows 8) by utilizing the virtual switch extension feature.

As the diagram above suggests, the Nexus 1000v relies of a installation of System Center Virtual Machine Manager to manage the extended virtual switch. I personally am a little disappointed by this as a System Center license kills the monetary advantage Hyper-V has over ESX/ESXi not to mention System Center is no walk in the park to set up. None the less in the next couple of weeks I will be installing and playing with the beta release of the Nexus 1000v in my home lab.

To participate in the Nexus 1000v beta for Hyper-V, firstly ensure you have a valid Cisco.com ID and password and send an email to [email protected].

Once you have been accepted into the beta program head to https://communities.cisco.com/community/technology/datacenter/nexus1000v/hyper_v_beta to download all the necessary packages and start playing.

  1. Regarding your comments around requiring System Center could be more political than a technical requirement. Require a paywall essentially before Microsoft allow you to deviate from their switch construct. Great writeup mate. Look forward to your dive into NX-OS from a System Administrations point of view.

      You raise a interesting point, ‘sure, move from a Microsoft only environment but give us some coin first’. It’s also a platform to get more people into the System Centre world which they are pushing very hard since 2012’s release.

Helpful? Have a question on the above?
