My VMworld Schedule

Here’s my VMworld 2007 schedule so far. I’ll update this as my schedule evolves. If anyone has any suggestions for other sessions I should attend, please let me know in the comments.

SUNW to JAVA

I’m not a Solaris expert, nor a SPARC expert, nor even a longtime user of their products. But I do have a lot of respect for their recent engineering efforts in the x86 space, particularly those hardware products released since Andy Bechtolsheim’s return with the acquisition of Kealia a couple of years ago. The move to open-source Solaris, the increasing visibility of OpenSolaris, the introduction of exciting new technologies such as ZFS…all these things have been building up the “tech cred” that Sun needs to win back (or continue to hold on to) the hearts and minds of technical leaders. And then this happens—they announce they’re changing the stock ticker symbol from SUNW to JAVA. Huh?

User Profile Management in VDI Deployments

In a “traditional” (as if that word can really be applied to a new technology use-case like this) VDI deployments, we’d use roaming profiles to have users’ settings follow them from hosted desktop to hosted desktop. In this article using the Flex Profile Kit (FPK) in a VDI deployment, I described an implementation in which roaming profiles couldn’t be used, and so we had to resort to the use of the FPK (which, incidentally, works well). There is, however, one problem: leftover profiles.

Listing All Unique MailTags Keywords

After figuring out yesterday how to list all the unique MailTags projects in use, today I worked out how to list all the unique MailTags keywords in use. As it turns out, it wasn’t as hard as I had suspected that it would be.

Listing Unique Projects Used by MailTags

Spurred to see if I could become more efficient than I am currently, I’ve been experimenting with some GTD-style applications. As a result of my experiments, I found that I needed a list of all the MailTags projects I’ve ever used in any of my mailboxes. (To make a long story short, I want to use the same project names across all applications—Mail, GTD application, Spotlight comments for files, etc.) While you can see a list of projects in the Preferences, that list does not include all projects that might ever have been used.

Failed Disks with the Data ONTAP Simulator

Last year I wrote about using the Network Appliance Data ONTAP Simulator on ESX Server, and in the comments to that article a number of people indicated that they’d been having problems with adding disks to the Simulator. The disks they added would show up as failed, and therefore couldn’t be added to any aggregates or volumes.

Error Connecting to VM Console

During an upgrade of a server running ESX Server 3.0.0 to ESX Server 3.0.2, we also moved the server to a new server room on a new subnet. The upgrade itself was uneventful and took only a few minutes (as I had expected), but what happened afterward caught me a little off-guard, as did the eventual solution.

XenSource Bidding War

Several virtualization-related blogs are commenting on this article by The Deal titled “Redmond to spoil XenSource buy?”. Is Microsoft preparing to launch a bidding war for XenSource, or are they content to allow Citrix to gobble up the small virtualization company?

The Linux Kernel, Binary Modules, and ESX Server

As a systems engineer for a value-added reseller/systems integrator, I’m often called upon to perform both pre-sales work as well as post-sales work. I do a lot of work with VMware (in case you hadn’t guessed by now!), and so a lot of the pre-sales meetings in which I am involved often center around VMware, its product offerings, and the benefits that virtualizing with VMware can offer a customer. One question that frequently arises during these kinds of meetings is, “Isn’t VMware based on Linux?”

VMware Addressing Virtual Security Concerns

One of the recurring complaints with highly virtualized environments is security. I’ve written about virtual security concerns before, and the resulting discussion (see the comments to that article) brought up some additional viewpoints as well. My opinion is that many of the “concerns” about highly virtualized environments are only concerns if you aren’t properly designing and implementing your virtualization environment correctly. (Of course, that statement is true for many, many technologies, not just virtualization. The same could be said for such technologies as firewalls, Active Directory, or handhelds/PDAs.)
