Host Profiles – Number of ipv4 routes did not match

As we have setup a new cluster of four ESXi 6.5 hosts, we have extracted a host profile from one of the hosts that we have setup to my customer corporate standards. After applying that host profiles to the other three hosts, we were able to quickly resolove all non-compliant issues except one where it keep complaining: “Number of ipv4 routes did not match”.

There is a good KB article on this which can be found at:

We had two challenges with KB2106112 though, which I wanted to document to help others stumbling with the same issue as follow:

1- The KB state it is only covering up to vSphere 6.0, where our environment was vSphere 6.5 and the fix still apply

2- The KB only stated to look at the “defaultTcpipStack” Netstack Instance, where in our case it was more to do with the “VMotion” Netstack Instance. Exactly same resolution, but you need to apply it to the “VMotion” Netstack Instance.

As I have mentioned above, this can affect any of your Netstack Instances, so while I am demonstrating how to fix it for the “VMotion” Netstack Instance, you can follow exactly the same steps to fix it for other Netstack Instances include the “defaultcpipStack”.… Read More

Software Defined Datacenter is a Game Changer

At VMworld, VMware will be blasting the world with its Software Defined Datacenter (SDDC) story. While VMware is at the center of the Software Defined Datacenter story, the VMware Software Defined Datacenter offering could put VMware at the Center of the IT Universe. The Software Defined Datacenter story remind me a lot of VMware initial virtualization story, where it had disrupted & changed the IT world for ever.

It was funny how the world play it self again, as I remember how much resistance VMware had initially of the Servers hardware vendors who were so worried that this new way of Compute  (Virtualization) could make them irrelevant. The benefits of Virtualization was unstoppable that it spread like fire that other vendors had to try to book their seat as quickly as possible to benefit of this technology change as they can not resist it any more. The nice part of the story virtualization end up pushing all these hardware vendors to innovate which has benefited both customers as well the different hardware vendors.

I am already seeing things shaping up in the same way at the moment with SDDC, as it will not just reshape compute, but it will extend to network & storage.… Read More
