Upgrade Distributed Virtual Switch (dvSwitch) from 4.0.0 to 4.1.0 in VMware vSphere 4.1

After you’ve upgraded your virtual environment to vSphere 4.1, you’ll have the option of upgrading your dvSwitch to version 4.1, too. This will give you 2 new features, namely Load-Based Teaming and Network I/O Control.

In your network overview, click your dvSwitch.

Click Upgrade to upgrade your dvSwitch to 4.1. Mind you, there is no going back, so double check if you really want or need this.

You are notified of the new features.

The software checks your hosts for the correct vSphere version.

And click finish to complete the upgrade.

The upgrade will be done in less then a second.

Unfortunately, I cannot test the Load-Based Teaming feature on my whitebox VMware cluster due to a lack of NIC’s.

Now, to enable Network I/O Control, go to the Resource Allocation tab of your dvSwitch. You’ll see it’s disabled by default.

Click the properties link on the right of the screen. In the popup window, enable Network I/O Control and press OK.

You will return to the previous screen and you can now see that the feature is now enabled. All done =)

    Thanks! that was just what I was looking for.

  2. Jeff Schoby says:

    Is the upgrade disruptive? e.g.: Will it interrupt network traffic to the VMs on the host when it upgrades the vDS code or does it migrate the running VMs off to another host, go to maintenance mode on that host, then upgrade it?

  3. Mukesh Baphna says:

    VMware’s VDS upgrade doesn’t affect VM/host networking and neither does the host go to maintenance mode.
