VMware logs – locations and what’s in them

December 19th, 2008

I was looking into an issue following an upgrade to vCenter Server 2.5 last weekend.  So I set about searching through the file system for the log files on the server with very little luck to be honest.

I then found two excellent posts from Rick Blythe a.k.a the vmwarewolf,  the posts detail the locations of the logs and what each one means.  This is an excellent post and one that I’m going to keep handy for all those strange little issues where insight into the logs might give a clue to the problem.

Virtual Center Upgrade – 2.0.2 to 2.5 Update 3

December 14th, 2008

Well this weekend I had the job of updating our Virtual Center deployment from 2.0.2 to 2.5 update 3. The primary reason for this was to prepare for the introduction of ESX 3.5 hosts into the Virtual infrastructure.

Due to the importance of our Virtual infrastructure I decided to do as much reading and preperation as possible to ensure it all went smoothly. It’s easier to convince our change management team to let us make changes if we get them right first time,  so this one was important to facilitate an easier path for future change.

So what did I read to ensure I’d covered everything,  here are a few links to get you started

vCenter Server 2.5 Update 3 – Release Notes

ESX 3.5 and vCenter Server 2.5 Upgrade Guide

The above PDF is a brilliant guide to the process you should follow, including rollback.  You should read this thoroughly so you understand all the pre-requisites and can avoid those silly problems that could cause your upgrade to fail.

Of course vCenter Server 2.5 introduces Update Manager. Although we can’t use it as we have ESX 3.0.1 and 3.0.2 hosts ( supports 3.0.3, 3.5 and 3.5i only ) I decided to install it anyway so it’s there for the future.

Here are some of the links I used to plan out my update manager deployment.

One of the main mistakes that people tend to make is to not give the SQL accounts the correct permissions on the new update manager database and the MSDB database.  Make sure you cover this one or you upgrade will fail.

It all went quite smoothly, I initially had a couple of issues which appeared to be related to me attempting to do a custom install. I wanted to ensure I could go through all settings and customise as required, the install however failed with various MSI error messages. I started the install again and didn’t choose the custom setup this time. This however created an issue whereby the Update Manager database appeared to install as SQL Server 2005 Express.  I wanted to put it on the same SQL 2000 server as our Virtual Center database but I never got the option as far as I can remember.  I have today uninstalled Update Manager and re-installed it using the “use an existing database” option and the SQL 2000 database.  It worked fine the second time around.

No immediate problems following the upgrade,  I had read some horror stories about issues with the Virtual Centre Agent on the host not updating.  Luckily for me it wasn’t an issue. Good luck with your upgrade

RVTools – Excellent VM Management Tool

November 13th, 2008

I’ve been neglecting the site recently due to the day job commitments,  so I’m going to make the effort and get a few articles up over the next few days.

I was trawling my igoogle feeds as I do every lunchtime and came across an article by Duncan Epping over at www.yellow-bricks.com on a tool called RVTools written by Rob de Veij.

In essence it’s a .NET 2.0 application that utilises the VI SDK to display information on your virtual machines.  You can access ESX 3.x directly or connect to VirtualCenter 2.x and list information on your VMs such as CPU, Memory, disks, nics, cd-rom, floppy drives, snapshots and vmware tools.

I gave it a quick go this lunchtime and am very impressed,  it provides a good deal of information and the snapshot, vmware tools and CD-Rom tabs are worth their weight in gold.  I’ve always been frustrated when trying to locate which VM is currently connected to an ISO image that I want to move or delete,  this tool was perfect for this problem.  I found that quite a few of my colleagues aren’t the best at disconnecting CD-Roms and I can include myself in that group as I always forget.  Nice to have a tool that simplifies the process.
