In San Francisco Before VMworld

Before I embarked on the busy schedule that is VMworld this year in San Francisco, my wife and I spent the day today strolling leisurely around the city. Before we’d even known it, we’d covered a total of about 6 or maybe 7 miles on foot, and seen more of the city than we’d planned on visiting today.

New Theme!

I finally got around to installing a new theme here on the site. I was both eager to install a new theme—after all, how many thousands of other sites looked just like this one—and yet also apprehensive, because I’d gotten the previous theme tweaked just the way I wanted it.

Invalid Configuration Error Creating New VMs

Earlier today, I was in VirtualCenter and needed to create a new virtual machine (VM). As this VM was going to be for purely scratch purposes, I wanted to use some local storage on one of the ESX servers. There was no need for VMotion, or DRS, or HA; it was a non-critical workload. So I right-clicked on the cluster, selected “New Virtual Machine…”, and started walking through the wizard to create a new VM. When prompted for storage, I selected a local datastore. Upon the end of the wizard, I clicked Finish, and was promptly greeted with an error message stating:

Solaris 10 Update 4 on ESX Server

I’ve been looking forward to Solaris 10 8/07 (Update 4) for a while now, eager to see what new technologies and features have been baked into the stable Solaris 10 code base. I won’t go into all the new bells and whistles, partly because I’m just not knowledgeable enough about them to them justice, and partly because it’s been done better elsewhere.

NetApp Suing Sun over ZFS

I was on the road most of the day today, so I must have missed this news earlier. Apparently, Sun Microsystems and Network Appliance have had a little spat over ZFS and WAFL, and now NetApp is suing Sun for patent infringement.

CentOS 5 on ESX Server

As I had to rebuild some Linux VMs in the lab anyway (they’d gotten messed up with various interoperability tests), I decided to try version 5.0 of CentOS. I was trying to get this done on Friday before the long holiday weekend, but it turns out that downloading the ISO images for six (yes, six!) CD-ROMs takes a bit longer than I had hoped. So I downloaded them at home on my 6Mbit DSL connection over the weekend, and had the opportunity to work on it yesterday while at the office.

Liveblogging from VMworld 2007

Like Alessandro at virtualization.info and Vincent at Virtrix, I’ll be liveblogging next week from VMworld 2007 in San Francisco, CA, USA. (I actually thought I had announced this fact in a previous blog post about VMworld 2007, but I went back and looked and apparently I didn’t. Go figure.)

Something About This Just Doesn't Seem Right

First, let’s set the stage. I first became aware of this issue—network slowdowns when playing multimedia files in Microsoft Windows Vista—when this article by Adrian Kingsley-Hughes at ZDNet popped up in one of my NetNewsWire subscriptions. I read the article and found that I was apparently coming in on the middle of an ongoing story, so I read Mark Russinovich’s response to the slowdowns with Vista. As usual, Mark’s work was concise, clear, very informative, and well-written. Seeking more information, I then turned to an article by Larry Osterman (apparently a Microsoft multimedia developer) with more details on the issue.

VLAN Interfaces with OpenBSD 4.1

I’ve been doing some interoperability testing with VMware ESX Server and VLANs (a separate article on that is in the works), and needed a guest OS that supported VLAN interfaces. From my previous (but limited) experience with OpenBSD, I suspected that VLAN interfaces were indeed supported, and after setting up a quick VM running OpenBSD 4.1 I found that I was indeed correct. Not only are they supported, they are incredibly easy to setup and configure.

SWsoft Disagrees with CNET Benchmarks

Via David Marshall over at VMblog.com, I picked up this article about SWsoft disagreeing with some CNET benchmarks. The benchmarks in question were comparing VMware Fusion, Parallels Desktop (keep in mind that SWsoft owns Parallels, if you didn’t already know that), CrossOver Mac, and Boot Camp.
