Dell’s announcement last week of the VMware Cloud on Dell EMC managed service offering is a game changer for enterprise IT in the medium / large / enterprise space. VMware announced it will sell a managed service offering consisting of VMware ESX, vSAN, VXRail, and a few other components in a rack that gets delivered to customers for a monthly fee. VMware will then leverage the skills they have gained in managing customer systems via the VMware on AWS service to customers who subscribe to this on-premises data center product. This brings multiple cloud benefits to the local data center. The move recognizes that some customers prefer gear to be onsite, yet they still want the flexibility provided by the cloud subscription model.Read More
One week from now I’ll be in Austin as part of the Tech Field Day delegate crew for Tech Field Day 18. This is my second Field Day event having attended Cloud Field Day 4 in Silicon Valley last year. I remember being completely terrified going into the trip. I had no idea what to expect. Sure, I’d watched presentations over the internet for years, but I hadn’t considered what happened once the cameras stopped rolling. It’s also fair to say I suffered from a fair bit of impostor syndrome. I didn’t feel my voice was as strong as the other delegates’. I couldn’t have imaged the sense of camaraderie, conversations, and history gained from attending.. Long story short, it turned out to be one of the most fun work-ish experiences I’ve had in my adult life.Read More
Today, ran across an error that I was previously unfamiliar with when running VMware workstation. The error occurred on my Windows 10 laptop with Workstation 14. The error read "VMware Workstation and Device/Credential Guard are not compatible. VMware Workstation can be run after disabling Device/Credential Guard." and was displayed as attempted to power on the VM.
A quick google search took me to a vmware KB article (https://kb.vmware.com/s/article/2146361) that lists the cause as "This issue occurs because Device Guard or Credential Guard is incompatible with Workstation." The fix, however, leads to a more general cause - VMware Workstation isn't compatible with Hyper-V. When reading through the fix, the advice starts with instructions for explicitly disabling the "device guard" feature. But then later on, the instructions state to uninstall the Hyper-V role completely. A few more google searches led me to discussion groups where people see issues running the two hypervisors on the same pc. It seems odd in 2018 that this would be an issue, but it seems to be true.
There was a time when I would have done this as I generally prefer the way Workstation handles vms and networking to hyper-v on a laptop. The problem here is that Docker for Windows 10 uses Hyper-V. So the decision isn't just VMware Workstation or Hyper-V, it's VMware workstation vs. Hyper-V AND Docker. Since I'm doing more with learning containers, I elected to not use VMware workstation.
VMware recently released an entry level exam for data center virtualization professionals called the VMware certified associate 6 - data center virtualization (VCA6-DCV). This certification is an update of the previous version 5 certification. The VCA-DCV based on vSphere 5 is due to be retired on November 30, 2015. VMware recommends those interested in the VCA6-DCV exam first complete a course called Data Center Virtualization Fundamentals.
I took this course as it was recommended by VMware as preparation for the exam. The course is offered online for free and can be accessed right after registering for the class. The course is available for quite a few months after signing up – helpful for those who might not be able to complete the course right away. Even if one couldn’t finish the course in the allotted time, it’s free, so one could simply sign up for a second time. The class takes a few hours to complete and can be started and continued multiple times.
The course doesn’t offer any hands on exercises. I say this up front because it communicates something about the type of course this is. This class is meant to familiarize the student with the language of VMware. There’s much here to familiarize a person with the dictionary of terms related to the various features one should know and where they fit within an enterprise. The course excels at providing basic to intermediate concepts related to vSphere 6 and providing thoughts on the applicability of those features in a typical enterprise datacenter.
There are many people who could benefit from the type of information in this course. It could be especially beneficial to those who need a high level understanding of VMware. Network, storage, and server engineers who work with and support virtualization engineers will find this helpful. It’s also good for those looking to move up in their IT career from other positions though they may need to put in time reading about the other topics outside of virtualization that are discussed. C-Level executives will also find the content appropriate as it explains many features that VMware feels differentiate them in the marketplace and make the VMware hypervisor more than a commodity datacenter technology.
The session is less helpful for experienced VMware admins / engineers who are looking for explicit how-to type of instructions, or really deep understanding of the limitations of the features and concepts presented. The objectives of the course modules are centered on the words, “describe” and “explain.” The course could be used as a form of “What’s New” learning opportunity as the cost is free.
