VMware has released Update 4 of the VirtualCenter Management Server (also now known as vCenter). The latest Release Notes detail a couple new features, several Plug-In updates, and numerous resolved issues. The current build of ESX/ESXi 3.5 Update 3 has not changed as of this post.

The following cut and pastes were taken while skimming through the release notes and highlight the changes that caught my attention.

What’s New

• Guest Operating System Customization Improvements – VirtualCenter now supports customization of Windows Server 2008 guest operating systems.
• Performance Overview Charts – VirtualCenter 2.5 Update 4 introduces the Performance Overview plug-in, which provides a single view of key performance metrics for CPU, memory, disk, and network without having to navigate through multiple charts. The aggregated charts show high-level summaries of resource distribution.

Plug-Ins Updates

This release of the VMware Infrastructure 3 software suite also includes the following:

• An update to VMware Converter Enterprise. For more information, see the VMware Converter Enterprise Update 4 for VirtualCenter 2.5 Release Notes.
• An update to VMware Update Manager. For more information, see the VMware Update Manager 1.0 Update 4 for VirtualCenter 2.5 Release Notes.
• The Performance Overview plug-in.

Two builds of VMware Infrastructure Management Installer are available for download.

• VMware-VIMSetup-2.5.0-U4-English.iso or VMware-VIMSetup-2.5.0-U4-English.zip – These files include an English-only version of the VI Client, which runs in English regardless of the language of the Windows system. Use this installer to install a VI Client that will run in English on Chinese, German or Japanese versions of the Windows operating system.
• VMware-VIMSetup-2.5.0-U4-localized.iso or VMware-VIMSetup-2.5.0-U4-localized.zip – These files include a localized installer that installs all files needed to run in English, Chinese, German, or Japanese. The VI Client used at runtime will correspond to the locale of the current Windows operating system if the locale is Chinese, German or Japanese. On Windows operating systems set to locales other than Chinese, German, or Japanese, the English version of the VI Client will be used.

Duncan over at Yellow-Bricks.com just a posted about a technology preview of the new VMware vCenter 2.5 for Linux available for beta testing. The virtual appliance can be downloaded from the VMTN forums in both .zip and .ovf format.

This early edition is for beta testing only, and VMware strongly suggests not to use this edition in a production environment. There is also a vCenter on Linux install guide .pdf available for download.

I’m looking forward to my current download completing so I can explore vCenter on Linux. I will not be able to post anything immediately as verbiage from the download page clearly states this technical preview is “highly confidential”.

Hopefully this is the start of some exciting new product announcements and features to coincide with the opening day of VMworld Europe 2009 tomorrow!

My recent post Why not VirtualCenter with SQL 2005 Express? explored the possible reasons for and against small and medium businesses (SMB) using the default, free database with VirtualCenter. But what happens if your virtual infrastructure implementation grows beyond 5 hosts and 50 virtual machines (VM), or what if you are close to the SQL 2005 Express database size limit of 4 GB? When it’s time to upgrade to a licensed version of SQL 2005 you can upgrade your VirtualCenter SQL 2005 Express database instance in place.

What happens when I outgrow SQL Express for Virtual Center? is a post from the VMGuy Blog by Dave Lawrence that provides the simple instructions to perform the upgrade in place. Read dave’s entire post, but here is a cut and paste of the VMGuy’s recommended upgrade steps. Read the rest of this entry »

As of VirtualCenter 2.5 (VC) MSDE was replaced by SQL 2005 Express as the default installation database. This post explores the idea of running small and medium business (SMB) VMware virtual infrastructure (VI) environments with the free SQL 2005 Express version instead of  a fully licensed instance of SQL 2005/2000.

To start with VMware’s VI3.5 and VC2.5 Installation Guide states:

The Microsoft SQL Server 2005 Express database package is installed and configured when you select Microsoft SQL Server 2005 Express as your database during VirtualCenter installation or upgrade. This is shown in Installing VMware Infrastructure Management Software. No additional configuration is required.

If Microsoft SQL Server 2005 Express is already installed, review the required database patches specified in Table 2-1. If you do not prepare your database correctly, the VirtualCenter installer might display error and warning messages.See www.microsoft.com/sql/editions/express/default.mspx.

Note: Microsoft SQL Server 2005 Express is intended to be used for small deployments of up to 5 hosts and 50 virtual machines.

5 ESX hosts and 50 VMs is definitely enough support for most small business deployments. Frankly, with modern hardware pricing the 50 VM limit will be reached before ever deploying 5 ESX hosts. 16 guests on a host is a common scenario these days which, if you do the math, creates a 3 host ESX Cluster.

So why would a company that does not expect to grow it’s number of VMs beyond 50 not use SQL 2005 Express? Here’s the 2 best reasons I could think of, and then a counter argument for each. Read the rest of this entry »

Eric Sloof’s A whiter shade of green is an informative post about how the Maps tab in VMware VirtualCenter (VC) can be used to visually confirm if a VM can be live migrated between ESX hosts. By selecting a VM in the tree explorer of VC and then clicking the Maps tab (not the Maps button), you can see a diagram of all of the ESX servers, virtual networking, and storage that must be consistently shared between hosts for VMotion to succeed. As my borrowed version of Eric’s orignal screen shot image shows, when all are configured correctly the ESX hosts have green circles around / behind them.

When the green circles do not appear, the Maps view helps troubleshoot what is wrong because you can see exactly which pieces are not connected correctly in the diagram.

What I did not realize, and Eric’s post points out, is that Read the rest of this entry »

I was surprised to discover that the ability to estimate the size needed for the VMware VirtualCenter (VC) database was built in to the VirtualCenter Management Server Configuration options in VC 2.5. This means that the next time you are asked by your DBA “How big a database does VC need?” you can answer that question from the convenience of your VI Client.

Just point the VI Client at your VC 2.5 server and then use the Administration MENU (not the administration button). Select VirtualCenter Management Server Configuration. Then click on Statistics.

Here’s a screen shot from a VI Client pointed at a VC 2.5 Update 3 server. Read the rest of this entry »

So you’ve downloaded your free version of ESXi. Maybe you’ve built a couple of ESX Servers but you haven’t purchased a full VI 3.5 Enterpise license. You might even have an enterprise license but your VirtualCenter (VC) server will be a virtual machine (VM) and you want to build a template VM as a gold image first. These are some of several possible scenarios where it helps to have VC -like functionalities without VirtualCenter. This post is a summary of 3 freely available tools that can provide some of VirtualCenter’s features.

First let me state that there is not an exact substitute for VirtualCenter, and the automation and ease of management VC provides is well worth it’s cost. Now for some alternatives. Read the rest of this entry »
