Vendor Meetings at VMworld 2013

This year at VMworld, I wasn’t in any of the breakout sessions because employees aren’t allowed to register for breakout sessions in advance; we have to wait in the standby line to see if we can get in at the last minute. So, I decided to meet with some vendors that seemed interesting and get some additional information on their products. Here’s the write-up on some of the vendor meetings I’ve attended while in San Francisco.

Introducing Linux Network Namespaces

In this post, I’m going to introduce you to the concept of Linux network namespaces. While it might seem a bit esoteric right now, trust me that there is a reason why I’m introducing you to network namespaces—if you, like me, are on a journey to better understand OpenStack, you’ll almost certainly run into network namespaces again.

Thinking Out Loud: DIY Network Virtualization?

Following on the heels of this week’s VMware NSX announcement at VMworld 2013, I had someone contact me about a statement this person had heard. The statement claimed NSX was nothing more than a collection of tools, and that it was possible to get the equivalent of NSX using completely free (as in speech and as in beer) open source tools—specifically, IPTables, StrongSwan, OpenVPN, and Open vSwitch (OVS). Basically, the statement was that it was possible to create do-it-yourself network virtualization.

Well, the title kind of says it all—yes, there will be an update to the popular Mastering VMware vSphere 5 book, with new content for the vSphere 5.5 release announced today at VMworld. Availability of the new title is expected in late October or early November, but I believe it’s already available for pre-order on Amazon.

Learning NVP, Part 4: Adding Hypervisors to NVP

This is part 4 of the Learning NVP blog series. Just to quickly recap what’s happened so far, in part 1 I provided the high-level architecture of NVP and discussed the role of the components in broad terms. In part 2, I focused on the NVP controllers, showing you how to build/configure the NVP controllers and establish a controller cluster. Part 3 focused on NVP Manager, which allowed us to perform a few additional NVP configuration tasks. In this post, I’ll show you how to add hypervisors to NVP so that you can turn up your first logical network.

Accessing VNC Consoles of KVM Guests via SSH

About a year ago, I published an entry on working with KVM guests, in which I described how to perform some common operations with KVM-based guest VMs (or guest domains). While reading that article today (I needed to refer back to the section on using virt-install), I realized that I hadn’t discussed how to access the VNC console of a KVM guest. In this post, I’ll show you how to use SSH to access the VNC console of a KVM guest domain.

State of Dev/Test Infrastructure Survey

While I was in the Bay Area a couple of weeks ago, I had the opportunity to sit down and chat with Navin Thadani and Shruti Bhat of Ravello Systems. Ravello, as you may already know (see this overview from Maish Saidel-Keesing or this post-Toronto VMUG wrap-up from Eric Wright), recently went GA with their technology. It’s pretty cool stuff, if I may say so.
