Third installation of this popular post comparing Nutanix Acropolis Hypervisor (AHV) and Vmware vSphere Hypervisor. This version is based on Nutanix AOS 5.5 version. Earlier versions of this post can found by clicking following links: 4.6 and 5.0.
There are still some use cases where using Vmware with Nutanix platform is required. But the list is getting smaller and smaller and there are less and less reasons to pay hypervisor licensing fees.

Finally got my hands on AOS 5.5 and upgraded our lab Nutanix cluster to this version.
In my earlier post I described how to manipulate “iptables” rules to allow access to “Stargate” or “port 2009” pages. Stargate page contains lots of detailed information of I/O operations, more info in my earlier post. It seems that “iptables” configuration has changed in this version.
In versions prior AOS 5.5 “iptables” chain used was called “WORLDLIST”. In AOS 5.5 the name of the chain has changed to “MGMT_OPENFROMALL”. This requires changes in “iptables” commands used.

For some reason I managed to upload images into Nutanix AHV image catalog that were corrupted. This might be a browser related issue, I have to do some digging in order to find root cause for the problem.
One symptom of image corruption was that all the controls for the image were missing from the Prism GUI. The image was there, but no controls and there was no way to remove the corrupted image.
- Login into one of the CVMs as nutanix user
- Launch acropolis CLI: acli
- List images: image.list
- Delete images: image.delete

Got one of our Nutanix demo boxes back from the field a while ago and set it up again in our demo lab.
Our lab network is VLAN segmented and the last time I did similar exercise, I had to set Acropolis Hypervisor (AHV) to send tagged frames also for management (CVM/Hypevisor) traffic. Instructions for this can be found from Virtual LANs for your Acropolis Hypervisor Virtual Machines. This includes modifying bridge “br0” on all AHV hosts , one AHV host at time. And setting each Controller Virtual Machine (CVM) to use VLAN tagging.
However in the post above Nutanix recommends CVM and Hypervisor traffic to use “untagged” (or native VLAN).
I was wondering whether you could use native VLAN setting for management traffic by modifying switch configuration and skip making changes to AHV hosts and CVMs. It would be much easier especially if you have many AHV hosts. Just log in to your switch and make changes in one place rather than logging into each and every AHV host / CVM separately.

March 15, 2017 update notes for Visio by DPTPB stencil collection
- Completely rebuilt/redesigned DPTPB Nutanix Visio stencil
- Bye-bye for original Nutanix rear view shapes
- I was never a fan of the original raster image based Nutanix shapes
- So I made my own modular vector image based Nutanix rear view shapes
- All rear view Nutanix DPTPB Visio shapes come now with connection points for easier shape placement
- Separate NIC shapes
- Data is now within top-level shapes
- Like with all new style DPTPB shapes
- Easier to access “Shape Data” window by clicking top-level shape
- Not really a problem with Nutanix shapes, but was a major source of frustration with switch shapes
- Now both Nutanix and Switch shapes behave similarly
- Both front and rear view shapes

March 15, 2017 update notes for Visio by DPTPB stencil collection.
This release is geared more towards ease of use of existing DPTPB Visio stencils rather than releasing many new shapes. There are some visual improvements, especially with Nutanix stencil, no more blurry raster based shapes, I’ve built my own vector-based Nutanix shapes.
It may look like much haven’t changed, but the changes are quite dramatic under the hood. I’ve changed the way DPTPB Visio shapes are used and built, both for easier usage and shape maintenance. This took quite a lot of work, in fact so much work that I don’t simply have enough time on my hands to update all my stencils to new style in one go.
