VMworld 2018 Barcelona Highlights

Stephen Hackers from Hot Wired IT Solutions affiliate partner to HTG (Howell Technology Group) made the trip to VMworld Barcelona 2018 with Kevin Howell (HTG), Graham Wight (HTG) and Tony Cota.

Overview

Tech Experts Meetings + Design Workshops + Vendors + Hall Sessions = A great experience and excellent value for money.

Things I learnt…

  1. Download the VMworld App
  2. Book sessions early
  3. Register for a vendor party
  4. Participate where possible

VMworld through my eyes

  1. Download the app… Contains your pass, schedule, reminders, events, map, info and more.
  2. The photo every geek wants

3. Picked up my VMware vExpert 2018 goodie bag

 

4. Attended multiple design workshops. Signing NDA… Sorry no secrets being shared here.

5. Entered the Hackathon .. Joined an amazing team of 8 experts. (3rd place)

Chris Porter, Christopher Lewis, Colin Westwater, Dave Simpson, Dominik Zorgnotti, Gareth Edwards, Tony Cota and Stephen Hackers (Me).

We created and launched #PowerVKE. PowerShell module to deploy kubernetes. This was successful in taking 3rd place at the Hackathon

24 hours on from the Hackathon and Will PowerVKE name change to PowerPKS??

 

6. Meet the Vendors.

Quantum

 

7. Vendor party

Cohesity was our option

Great night out and some interesting glow in the dark / flashing devices for the night. The Queen tribute act was definitely worth watching. The friendly atmosphere was fantastic

 

8. Meet the Experts.

I attended two of these excellent sessions on PKS (kubernetes) and vSphere on AWS. As a techy I felt I got more business value in these 30-45min 1-1 tech sessions than in some of the high level presentations attended. That’s not to say the high level presentations were worth attending as well, but I got to ask in the 1-1 my homework for actual work I’m doing or planning on doing.

 

9.The End

Then the trip was over. Such an amazing few days. Already looking forward to VMworld 2019……

vSphere ESXi 6.7 Unable to talk between subnets between hosts

Configuration was :

ESXi 6.7 – vSphere handling all the port groups tagged with VLANs

Firewall – CISCO ASA

 

Problem : New ESXi 6.7 hosts. A virtual machine if on the same host and vSwitch could communicate no problem. However if a virtual machince was communincating with another virtual machine on another host on a different, subnet they were unable to communicate between subnets and hosts. Both virtual machines could ping their local gateways. Firewall, CISCO ASA was just dropping all packets and showing the following error

Error on the Firewall when capturing ping traffic “No source port  on ping “Error (Type 8, Code 0), Denied ICMP type=8, code=0”

 

Solution

Sometimes its the simple tick box on the Firewall / ASA config

“Enable traffic between two or more interfaces which are configured with the same security levels”

All traffic started communicating and the virtual machines could talk between the subnets as per the rules on the Firewall.

VMware vRealize – What is vRealize Orchestrator(vRO)?

Overview

This is my interpterion of VMware vRealise Orchestrator at a high level. VMware vRealise Orchestrator is a centralised location to create workflows, create actions and define configuration elements to automate tasks. In ddition there is a useful tool built-in which can auto generate documentation based on your workflows created.

so, how does vRO compare to my previous work?

My first impression of vRO, is the tool reiterates the structure I have been putting in place via PowerShell scripts on previous projects and demonstrations.

Previously I would create a simple CSV which contained all the server / virtual machine information

See my previous work on bulk virtual machine deployments:

The logic is :

Within vRealise the procedures are all done in work flows. Its worth noting scriptable tasks are in JavaScript. Scripts can be added to workflows

The scriptable tasks are more interesting. You can predefine properties/variables to use within the script tasks.

Some nice key features :

  • Descriptions area for workflows
  • Version control work flows.
  • Simple Output to System.log

Is there a similar alternative product I’ve used.

Some of vRO features do have similarities to an alternative product I have recently been using called Octopus. Octopus has the options to create processes, add scripts including PowerShell and version control each release and control releases.

Scripting
Moving on to more advance scriptable tasks in vRO, decisions can then be defined based on If …Else statements to define the output. When scripting within workflows, a simple but effective feature is when a variable is entered in a script, the variable name changes colour.

Out the box options
There are some out the box options such as VMware tools and Virtual Hardware upgrades with vRO workflows.
There are many more advanced topics and work flows. Feel free to share your favourite work flows or developed work flow on twitter @stephenhackers
