With virtualization come management challenges. Now that applications compete for shared, dynamic infrastructure resources such as storage, memory, and CPU, an inevitable resource allocation problem arises, that if not addressed will impact the performance of both VMs and their associated applications. This presentation discusses the 20 metrics that truly matter in vCenter to evaluate and manage this situation.
Watch this video to learn
- Which VMware metrics you should care about and why you can't ignore them.
- How they reveal issues that impact application performance.
- Ways to further analyze the data provided to fix issues and improve performance in your data center.

RVTools is a windows .NET 2.0 application which uses the VI SDK to display information about your virtual machines and ESX hosts. Interacting with VirtualCenter 2.5, ESX 3.5, ESX3i, ESX4i and vSphere 4 RVTools is able to list information about cpu, memory, disks, nics, cd-rom, floppy drives, snapshots, VMware tools, ESX hosts, nics, datastores, service console, VM Kernel, switches, ports and health checks. With RVTools you can disconnect the cd-rom or floppy drives from the virtual machines and RVTools is able to list the current version of the VMware Tools installed inside each virtual machine. and update them to the latest version.
Pass-through authentication implemented. Allows you to use your logged on
Windows credentials to automatically logon.
All numeric columns are now formated to make it more readable.
On vInfo the columns Commited, Uncommited, Shared and on vSnapshot the
column size are now formated in MBs instead of bytes.
New tabpage created with service console and VMKernel information.
Now using vSphere Web Services SDK 4.1 which supports the new features
available in vSphere 4.1
Export to csv file now uses Windows regional separator

This article is written by Ernst Cozijnsen.
A few days back after applying some patches via "Update Manager" we came to notice that our ESXi 4.1 host bacame unresponsive after a reboot. Loggin into the command prompt via ILO was unsuccessful too because the rootpassword was not working anymore. That just sucks!.... but nothing to get all emotional about since is just linux ;-) (well a sort of...)
Looking for a nice how-to explaining this i stumbled across the following article: http://www.vm-help.com/esx/esx3i/Reset_root_password.php
After doing the endless tar commands described in the article I rebooted the machines and what the ....... still not working. (And this is where I got frustrated since this is the only decent way to reset a security feature like this).
VMware states that it is impossible to reset a root password of an ESXi server in a supported way. Well.... let's see if we can bend that opinion.
Since VMware was so nice to give us "host profiling" I thought this was the time to look into it and see if we can use it in an alternative way. Chaning a root password without root permissions would normally be a serious security leak. OK, so the assumption is that the host you are having issues with was connected to vCenter and the account you are using has admin rights.
Execute teh following steps:
- Take a "similair" server and create a host profile from this machine
- Edit the Host profile and change the "Administrator password" to a fixed one
