So let’s say you aren’t one of the people who slips streams the latest service pack. If you want to use Windows XP in Hyper-V you need to install the Integration Services “disk”. You’d need this if you want to have the heartbeat functionality for example or actually connect to a network, these include the drivers. So yes, you will want/need to do this. The Integration Services will only install if you have XP SP3. So the question is, how do you get SP3 on a VM in Hyper-V when you have no connectivity? The answer, SP3 in ISO FORMAT. I love this. You are able to download the .ISO, connect the ISO to an IDE drive in the settings menu. SP3 is cumlative so if you have a disk pre SP1, yes that was me, after installing this you should be able to install the Integration Services and connect to the network.
