Poonen briefly recaps yesterday’s messaging, and then moves into the focus of today’s keynote—focusing on the “any application and any device” part of the “Ready for Any” messaging.

This is a liveblog for the Day 1 general session at VMworld 2015 in San Francisco. For many people, VMworld started yesterday with the Welcome Reception in the Solutions Exchange, but today marks the official kick-off to the event. I’ll have to end this liveblog shortly before the general session ends in order to make it to some customer meetings.

VMworld 2015 Prayer Time

Last year, a group of believers gathered for a brief time of prayer while at VMworld 2014. This year, I’d like to again offer believers attending VMworld 2015 the same opportunity to gather together for a time of prayer before starting the day. If you’re interested in attending, here are the details.

Using Vagrant and Docker Machine Together

In this post, I’m going to show you a quick tip I used today to combine the power of Vagrant with that of Docker Machine to quickly and easily create Docker-enabled virtual machines (VMs) on your laptop. This could be useful in a variety of scenarios; I leave it as an exercise for the reader to determine the best way to leverage this functionality in his or her own environment.

VLAN Trunking with Mikrotik RouterOS

In this post, I’m going to show you how to configure VLAN trunking with Mikrotik RouterOS, and along the way provide a brief introduction to this software and some of the functionality it offers. While it is Linux-based, RouterOS operates quite a bit differently than a lot of the other network operating systems with which I’ve worked, and so I hope that this post will help ease the learning curve a bit for others who decide to take the same path.

A Fix for Ubuntu Apparently Caching Network Configuration

I’ve been wrestling with an Ubuntu network configuration issue over the last couple of weeks (off and on between working on other projects), and today I finally found a fix for the problem. The issue was that Ubuntu wouldn’t pick up changes to network interfaces. The fix is so simple I’m almost embarrassed to talk about it (it seems like something that I should have known), but I’m posting it here in case others run into the same issue.

VLAN Trunking with Cumulus Linux

Following up on my earlier post on Cumulus Linux networking concepts, I wanted to build on that information with a guide on configuring VLAN trunking. This would be useful in a number of different scenarios: supporting multiple (VLAN-backed) port groups on vSphere hosts, or connecting an Open vSwitch (OVS) bridge on a KVM or Xen hypervisor to multiple VLANs. You might also need to use a VLAN trunking configuration to connect a Cumulus Linux-powered switch to another switch.
