New England Summer VMUG – Brunswick, ME

I attended the New England summer VMUG in Brunswick, ME on Thursday and I figured I would tell you all about it. Let me start by admitting that this was the first VMUG and I was shocked at the size and coordination of this invite. From what I heard, there were over 1,800 pre-registrations with about 1,200 people actually showing up. The event was sponsored by 40 vendors (30 breakout sessions!) and they went all out.
The agenda for the event is available here. Below are the notes I took during the event.

vSphere 4.1 Released!

I am sure by now you have heard the news that VMware released vSphere 4.1. This announcement comes just over a month after the release of vSphere 4.0 Update 2 and exactly as predicted by The vSphere minor update brings many new and exciting as well as enhanced features to the server-class product. Instead of discussing everything that is new (e.g., VAAI) or improved (e.g., vMotion and HA) and instead of highlighting what people may consider the most important touch points (e.g., memory compression, storage I/O control and network I/O control), I would like to talk about several details of the announcement that I believe will be overlooked and their significance.

Rooting / Flashing the Droid

I have just updated my Motorola Droid documentation available here: The biggest addition is information about rooting and flashing the Motorola Droid. Since I think this information will be valuable to others, I am including it in a blog post as well.
DISCLAIMER: Please be advised that rooting your phone WILL VOID THE WARRENTY! I am in no way responsible for what you do to your phone, but you should know you can permanently damage it so please proceed with caution. In addition, I can in no way take credit for this process, but I figured this article would be helpful as I found some of the directions online confusing.
WARNING: It is important to understand the difference between rooting your phone and flashing your phone. Rooting your phone gives you the highest permissions available on the system. For Linux this is equivalent to having root and for Windows it is equivalent of being Administrator. Rooting your phone does not remove any data from your phone. Flashing, on the other hand, changes the operating system the phone is using. In order to flash your phone you must root your phone first. Flashing almost always requires wiping all data off of your phone, but not the SD card. Once your phone has been flashed, it will lose all applications and information stored on it that was not saved on the SD card. One additional thing I would like to add is that flashing your phone takes quite a bit of time. For me, it took about three hours to back up, root, flash, install, and configure my phone, so plan accordingly.
I followed the instructions available at: and flashed my phone with assistance from my Windows XP laptop. The basic steps are as follows:

  1. Back up all data except contacts (assuming you have synced them with Google) and /sdcard on your phone
  2. Install Android SDK and USBDeview
  3. Install SPrecovery
  4. Take a full backup of the existing ROM on your phone (optional, but highly recommended)
  5. Copy backup off of the phone (optional)
  6. Root your phone
  7. Take a full backup of the rooted ROM on your phone (optional, but highly recommended)
  8. Install ROM Manager
  9. Flash your phone
  10. Take a full backup of the new ROM on your phone (optional)
  11. Install and configure new ROM

VMware Update Manager Issues

For those of you who have never had the pleasure of patching ESX prior to VMware Update Manager (VUM), be thankful. Prior to its inception, the process of patching ESX hosts was repetitive and extremely error prone as it was completely manual. Today, this process is fully automated, but that is not to say the automation does not come with its fair share of issues. In this entry, I will be focusing on a couple of VUM issues I have experienced and the troubleshooting steps I have taken to resolve them.
