Cocoalicious Development Restarted

This is really exciting news. Development on Cocoalicious, the Mac OS X native application that front-ends del.icio.us, has started back up again.

Update on Call for Prayer

A week ago, I posted a call for prayer for my family. I appreciate the many responses that I received, and I am happy to report that the Lord has answered our prayers. Although the answer did not come in the form that I had hoped, I am still thanking God for deliverance and I am praising God for his wondrous works.

VMware as Middleware

The author of this recent post suggests that using VMware as “middleware for the OS” provides an abstraction layer that can help organizations in a variety of ways:

Call For Prayer

I know that my weblog defies the “normal rules” of how one should run a weblog in that I freely mix both personal and professional topics on the same site. As I said in my very first post, I can’t hide who I am, and I am a Christian. If that means that my Christianity bleeds into everything else, so be it.

VMware Fusion Beta 3

The development team at VMware has released Beta 3 of VMware Fusion, and I had the opportunity to download and install the new version earlier this morning. Based on what I’ve seen so far, this is a solid improvement over earlier versions and the development team is making good progress on the product.

ESX Security Vulnerabilities

Within the last few days, VMware has acknowledged the presence of a number of security vulnerabilities within the flagship ESX Server product. At least two of these vulnerabilities were discovered during an internal security audit of the code, but it’s unclear how many of the rest were internally discovered or externally discovered and reported to VMware. There has been no indication that there are any publicly-available exploits for any of these vulnerabilities.

Open Source Virtualization Thoughts

Edward Aractingi started it all back on March 20 when he blogged about why VMware should open source ESX Server. Tarry Singh then weighed in on the matter from his weblog. Both men make very good points on the matter.

New VMotion Boundary

In an earlier article about VMotion compatibility, I mentioned that SSE support was a VMotion boundary, i.e., a host with SSE3 CPUs and a host with SSE2 CPUs would not be able to VMotion guests between them without first masking the SSE support bit. I used this technique myself in our lab (more info in this article), and this issue drew some attention as the result of a presentation at VMworld last year.

Using FPK in VDI Deployments

Many VMware Virtual Desktop Infrastructure (VDI) deployments will likely be environments where the virtual desktops will be the only desktops that the user ever logs into. Environments like outsourced development (developers use hosted desktops so that the source code never leaves the company’s equipment) and call centers are two examples that come to mind. A recent project in which I was involved, though, was a bit different: the customer wanted to use hosted desktops to provide access to a specific application (an application which was very data-intensive), but all other applications would be run from traditional “fat” PCs. Users would be logged in to both a traditional PC as well as a hosted desktop session, typically at the same time.

VDI and Leostream Connection Broker

For those that aren’t familiar with this latest TLA (three-letter acronym), VDI stands for “Virtual Desktop Infrastructure” and it’s an alternate way of utilizing virtualization in the datacenter. Instead of virtualizing server instances, we virtualize desktop instances, and then provide a means for users to connect in to one of these available instances. (You can learn more at VMware’s Virtual Desktop Infrastructure web page.)
