On one recent project, there was a pressing problem related to a browser issue which had to be tested and diagnosed very quickly with as much reliability as possible.
Our Lead Developer created a Virtual PC with Oracle’s VirtualBox
(latest version) technology and installed an obsolete operating system on it. This operating system was used by the client. Internet Explorer 7.0 was downloaded from the Microsoft web site and installed.
Why a Virtual PC?
A computer with the obsolete operating system was only needed for a few hours and the test to be carried out was software based. Furthermore, there wasn’t a spare PC in the office to install the operating system and browser.
Once a close-as-possible replica of the client’s computer had been made the problem as experienced by the client could be tested for. In the case concerned, the problem was reliably reproduced and a diagnosis made.
An attraction of VirtualBox
is being able to Remote Desktop into the Virtual PC – see above. Incredibly useful in some situations!
