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.)

Citrix to buy XenSource

It’s odd how things work out sometimes. I was in a meeting earlier today with our VMware channel SE and some other colleagues on our VMware team, and the subject of VMware’s relationship with Citrix came up. The VMware SE went on to explain that there was no head-to-head competition between VMware and Citrix, and that the two companies’ products were, in many cases, complementary. Fine, no big deal; I can buy that. I’ve seen a lot of instances where virtualizing Citrix Presentation Server offered value to the customer, even if it did mean a drop in the total number of users that could be supported on each (virtual) instance of Presentation Server. (The benefits of snapshots, cloning, VMotion, etc., are pretty compelling in some environments, and outweigh the decreased user session counts. But alas, I digress…)

Next-Generation Virtual Infrastructure

If the list of features in ESX Server 3.1.0/VirtualCenter 2.1.0 as exposed by virtualization.info actually make it into the shipping product, VMware will even more rapidly increase the gap between them and the rest of the virtualization market. The features list sounds like a “wish list” from virtualization customers far and wide:
