Virtualization Congress 2009 Sessions

I hadn’t really planned on identifying which of the Virtualization Congress 2009 session proposals were mine. I had originally thought I’d just let the proposals ride on the strength (or weakness) of the proposed content—along the same lines as Alessandro’s thoughts when he left the speaker names out of the session proposal list—but since it appears that numerous other potential speakers are plugging their sessions I’d better follow suit! After all, it’s only a level playing field when everyone is following the same set of rules.

Partial Case Sensitivity with esxcfg-advcfg

I was working on some documentation this afternoon that centered around the use of esxcfg-advcfg to set some NFS-related parameters in VMware ESX. While verifying the command syntax, I noticed something interesting about the esxcfg-advcfg command: it’s only partially case-sensitive.

Changing vNIC Port Group Assignment in VMware with PowerShell

Experienced PowerShell users won’t find this post very helpful, but less experienced PowerShell users—or even PowerShell newbies such as me—may find this handy. Today I had a need to change the port group assignment on the vNICs for a bunch of guest VMs in the lab. Rather than manually click through all these VMs just to change the port group, I decided to give PowerShell a try.

Ubuntu and Mac OS X Integration

One of my projects over the Christmas holiday has been to rebuild the home network. You’d think I’d want to avoid that sort of thing since I’ve been on vacation from work for the past two weeks, but working on a home network is a different sort of beast than working on a network for a company. There are different challenges to be addressed.

Blasts from the Past

I was visiting Unclutterer and saw them sharing older content from the site in a similar fashion. So, I thought I might try it here. Enjoy some of these “blasts from the past”!

One of the "Top Virtualization Blogs" of 2008

2008 was a great year for this site. Late this year, I broke over 3,000 RSS subscribers, and the site averages 5,500 to 6,000 page visits every day. Except for November, the site racked up over a million hits every month in 2008, totaling almost 15 million hits for the entire year. Wow! Thanks so much to everyone who reads, subscribes, visits, or otherwise supports my site.

OpenVPN and mt-daapd

I have a system at home with an “older” Linux distribution for mundane tasks like DHCP and content filtering on my broadband connection (no need for the kids to see something they shouldn’t be seeing, if you know what I mean). I’ve thought frequently about rebuilding it with a newer distribution, perhaps Ubuntu, but—to be perfectly honest—I’m just too lazy. It generally just works, and overall doesn’t require a great deal of care and feeding.

Merry Christmas!

Let us never forget the true reason behind Christmas:

Random Reboots with VMware ESX 3.5 Update 3

I’ve been communicating with a reader who is experiencing random reboots of virtual machines on his HA/DRS-enabled cluster running VMware ESX 3.5 Update 3. At first, I thought his problem was related to the bug with VM failure monitoring that I discussed here, but upon further discussion the random reboots are continuing to occur even when VM failure monitoring is disabled. The only relief the reader has been able to find thus far has been to completely disable VMware HA on his cluster, which—to be honest—is a less than acceptable solution.
