Problem with VMXNET3 Driver

A colleague on the EMC vSpecialist team (many of you probably know Chris Horn) sent me this information on an issue he’d encountered. Chris wanted me to share the information here in the event that it would help others avoid the time he’s spent troubleshooting this issue.

Giving Thanks on Thanksgiving

Here in the United States we are preparing to celebrate the Thanksgiving holiday, and it’s a time of reflection. It’s a time to be thankful for what we have and what we’ve been given. This past year has been a tremendous year for me, both personally and professionally, with lots of things for which to be thankful:

Exporting Outlines as Markdown

As you probably already know, I’ve been working extensively with Markdown (and MultiMarkdown) over the last few months, and it has rapidly become my preferred format for content creation. To help me more extensively leverage Markdown for all my content creation, I came across this OmniOutliner plug-in by Fletcher Penny that allows me to export outlines as Markdown.

Some vSphere 5 Video Content

While I was in Copenhagen for VMworld EMEA 2011, I ran into a few EMC colleagues from the Solutions Center in Cork, Ireland. I’d visited Cork a couple of times last year (haven’t had the opportunity this year, sadly), so it was great to catch up with them. During our conversation, one of them mentioned that the EMC Proven Solutions Group has a YouTube channel and had posted some new vSphere 5-related content.

vSphere HA and vApps

This is probably obvious to most everyone, but for those who don’t already know it’s important to point this out: vSphere HA does not honor vApp startup settings. So while you can go into the properties for a vApp and define the order in which VMs will start (or stop) and the timing between those actions, vSphere HA will not recognize or honor those settings. Therefore, in a situation where an ESX/ESXi host fails and that host is running a vApp, the individual VMs in the vApp could be restarted in an entirely different order than what you specified in the vApp settings.

Spousetivities at HP Discover Vienna

As many of you probably already know, my wife Crystal (@crystal_lowe on Twitter) runs something called Spousetivities, which organizes activities for spouses traveling to conference cities with conference attendees. (You can learn more about Spousetivities by visiting the About page.) In the past, Spousetivities was limited to VMworld. This past year, it expanded to include EMC World as well. And now it’s expanding again to include HP Discover Vienna!
