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

Written by Ingmar Verheij on September 27th, 2013. Posted in VMware

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 [email protected]. 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.

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

Written by Ingmar Verheij on June 11th, 2012. Posted in Performance testing

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”.

VMware shared folders keep profiles in use

VMware Shared Folders

When Microsoft Windows systems are virtualized with VMware ESX or Workstation, WMware Tools is installed. When the VMware tools are installed with the Complete option, the shared folders option is enabled. This feature is not enabled when you install VMware tools with the Typical option.

The shared folder feature is not supported by ESX or GSX server and causes problems on Terminal Servers. The file hgfs.dat is opened by the VMware Tools with exclusive acces, which prevents the profile from getting deleted.

Do we need ‘fancy’ features for VDI?

Written by Ingmar Verheij on October 30th, 2009. Posted in Desktop Virtualization

Everyone knows that more and more people are thinking about VDI, or at least they’re talking about VDI. And most of these people don’t really know what they’re talking about, what they really want and what they need. There are more usecases, solutions, alternatives which might be better for most of them.
In this article i’m talking about ‘hosted virtual desktops’, the way most people see VDI. The desktop is a virtual machine running on a hypervisor in the datacenter.

Yesterday I attended a presentation where VMware was talking about VMware View, there product for VDI implementations. In this presentation one of the key-features of VMware View was there ESX plaform, and all the ‘fancy’ features this hypervisor has. And with ‘fancy’ features I mean features like VMotion, High Availability, DRS and Fault Tolerance.
These are all great features and very usefull, in enterprise environments, for servers. In smaller environments these features aren’t necessary or even needed. In fact, in most enterprise environments not all features are really required, there used because “we can”.
