History of Cross vCenter Workload Migration Utility and its productization in vSphere 7.0 Update 1c (p02)

by // 35 Comments

I am super excited to share that the popular Cross vCenter Workload Migration Utility Fling has been officially productized and is now available with the release of vSphere 7.0 Update 1c (Patch 02)! The official name for this capability is now referred to as Advanced Cross vCenter vMotion, would that mean the short hand is Ax-vMotion? 🤔 In any case, this has literally been 5 years in the making from an idea that I had shared back in 2015 to now having it fully integrated as a native vSphere feature in 2020 is pretty wild!

While reflecting back and writing this blog post, I came across this tweet from our CEO, Pat Gelsinger, which I thought was quite fitting

I have learned over the years, that simply having a good idea is not enough. It takes hard work, time and perseverance.

It has been very humbling to work with so many of customers of all sizes and shapes and enabling them to take advantage of vMotion in a new way that would allow them to solve some of their unique business needs. vMotion is still as magical in 2020 as it was when VMware transformed the IT industry when it was first introduced.

Of course this would not have been possible without the support of so many amazing VMware Engineers who contributed to the Fling including the original developer, Vishal Gupta who I had worked with as part of the VMware Cloud Foundation (VCF) team. After Vishal left VMware, I recruited a few more folks to help with the project including Vladimir Velikov, Vikas Shitole, Rajmani Patel, Plamen Semerdzhiev and Denis Chorbadjiyski. Lastly, I also want to thank Vishwa Srikaanth and Abhijith Prabhudev from the vSphere Product Management team who have been supportive of the Fling since day 1 and has been advocating with me on behalf of our customers.

Troubleshooting tips for configuring vSphere with Kubernetes

by // 10 Comments

With more and more folks trying out the new vSphere with Kubernetes capability, I have seen an uptick in questions both internally and externally around the initial setup of the infrastructure required for vSphere with Kubernetes but also during the configuration of a vSphere Cluster for Workload Management.

One of the most common question is why are there no vSphere Clusters listed or why a specific vSphere Cluster is showing up as Incompatible? There are a number of reasons that this can occur including vCenter Server not being able to communicate with NSX-T Manager to retrieve the list of NSX pre-checks which would cause the list to either be empty or listed as incompatible. Not having proper time sync between vCenter Server and NSX-T which can also manifest in a similar behavior among other infrastructure issues.


Having ran into some of these issues myself when developing my automation script, I figure it might be useful to share some of the troubleshooting tips I have used when trying to figure out what is going on whether that is during the initial setup or actually deploying workloads using vSphere with Kubernetes.

Listing all Events for vCenter Server

by // 4 Comments

I had a conversation with one of our VMware Cloud on AWS field leaders a couple of weeks ago at reInvent on his initial experience with the vCenter Event Broker Appliance (VEBA) Fling. There were lots great feedback but one thing that stood out to me which looks to have been a barrier to getting started was being able to figure out a specific vCenter Event and its respective identifier. Although the list of "default" vCenter Events are documented in the vSphere API, it is definitely not the first place most folks would go to look nor is it very intuitive to browse.

To be honest, this is not a unique ask for VEBA. I have also seen this requests come up from customers who are automating vCenter Alarms, which can also be based off of vCenter Events and the same question has come up on before. One challenge with such a request is that the number and the types of vCenter Events will vary from customer to customer depending on the number of 2nd and 3rd party solutions deployed, not to mention it will also vary from version to version. In addition, as a customer, you can also publish your own custom Events into vCenter Server which makes this difficult to provide a single list that would cover all possible scenarios.

Ultimately, this ask is completely valid and I started to look at the vSphere API to see if there was something that could help. It did not take look before I stumbled onto the EventDescription which is part of the EventManager, which provides a nice registry for all currently registered vCenter Events. Time for some Automation 🙂
