How to reinstall VMware Tools on a ParaVirtual VM

At a customer location I was asked to reinstall VMware Tools on machines, normally the customer would do this their selves, but after uninstall of the VMware Tools, the VM wouldn’t boot. They needed to reinstall the VMware Tools because of the issue encountered described in  VMware KB2063887

vCenter Server 5.1 with SSO 5.5

This blog describes how to install vCenter Server 5.1 with SSO (Single-Sign-On) 5.5

In my case, it’s not possible to upgrade to vCenter Server 5.5 because of the fact that the vendor doesn’t support a higher version (yet).

SSO 5.1 (and i will say it very nice) is not the best product VMware has ever made.
It has several bugs and is not very stable.
But VMware made a more stable version for 5.5, and i recommend everyone to use that version.

Ok, this is the procedure to install all needed vCenter components: Read more

VMware: Recover vCenter Single Sign On (SSO) master password

VMware vSphere Web Client - vCenter Single Sign On InformationDuring the installation of the VMware vSphere Web Client I had to provide vCenter Single Sign On Information. Since no additional accounts / groups where granted SSO admin privileges (see VMware vSphere 5.1 Documentation Center)  the only account that had sufficient privileges was the default SSO admin user admin@System-Domain. The credentials of this account are provided during installation of the vCenter Single Sign On Service.

Unfortunately the password of the default SSO admin account was unknown. In this article I’ll explain how to change the password of the default SSO admin account.

Collect information about an ESX environment

This week I am creating an inventory of a customers network environment. Within the network of the customer is an VMware ESXi environment. While I am looking for an efficient way to collect information out of VMware vCenter I stumble upon a .NET tool called RV Tools from VMware vExpert Rob de Veij.

This tool gives you the possibility to collect information from your ESX  environment.

Snapshots present and growing, but not visible in Snapshot Manager

When using  a backup solution for your virtual environment and the database-server for this backup solution is also situated in the virtual environment, you have to face some challanges. The backup solution cannot back up its own database, while using it. Luckily there are work-a-rounds covering this particular problem. But what happens if you misconfigured this work-a-round? In this case snapshots will be taken of the database-server and will not get removed properly, resulting in snapshots on your datastore that keep growing and growing and you will not be aware of it, because the snapshot manager says there are no snapshots present.

Back-up for virtual environments (TSMVE) is still underestimated by IBM!

When you are using IBM equipment there is a big chance that you will use IBM related software to manage the environment. In a large  environment you can use IBM Tivoli Storage Manager (TSM) for Virtual Environments to make back-ups of your virtual machines. IBM says that:

Tivoli® Storage Manager software provides a wide range of storage management capabilities from a single point of control, helping companies ride the information tidal wave.

Early this year they’ve added a new product to the Tivoli Storage Manager, IBM storage management software called IBM Tivoli Storage Manager for Virtual Environments (TSMVE). This is their product for making back-ups and to recover virtual machines.

You would think that a big company like IBM jumped on the train of virtualisation when it was leaving the train station but in my opinion that’s not what they have done!

On premises DropBox



In our private lives we are already accustomed to using cloud based file sharing. Who of us isn’t using or has tried Dropbox? Dropbox was my first cloud based file sharing solution. In the time between now and then there are many new players in town like BOX,PogoPlug and many more. Where Box stores the files in the cloud, other store the files on premise like Pogoplug (for private use).

Now a days users are using solutions like Dropbox to store company data. Who thinks this is not happening, please get out of your cave. My customers, mostly in the top fortune or government, must be aware of the risks users are taking “without” knowing what risk they are taking. Even when a user knows the risk, they are willing to take it because of the flexibility it gives them! My advice: Think like a user! In some company’s the IT departments are still saying NO to the wish of the end user. But let’s be honest, the rules within the IT department are less restricted. And the end users (especially from generation Y) are consuming IT: they are demanding this flexibility. In my opinion these days IT is controlled by our users .Don’t try to control them, work with them. Watch and learn how they like to work, this is the only way you’ll be in control.

Virtual (SQL)server impaired by residual snapshot after Veeam backup

Author : Ingmar Verheij


Recently I had to troubleshoot a SQL server that performed nightly batch jobs for a management information system. Under normal conditions this required 6.5 hours but this was suddenly increased to 11.5 hours. An increase of 75%!

Because of this delay the information wasn’t presented on time with a lot of implications. Several departments where asked what has changed in the past days, of course the answer was “nothing”.

Thinapp: Child process keeps SandBox locked

One of the best practices when packaging with ThinApp includes verifying no processes are left running that lock the Sandbox when you shuts down the application. You can simply verify this by trying to delete the package’s Sandbox. If it is locked and you cannot delete it, some process is still running.
To determine wich process locks the sandbox i use Process Explorer.

In my case the child process ‘svchost.exe’ kept the sandbox locked.
Because it was running outside of the thinapp the ‘OnLastProcessExit function’ is never called.
