Anybody has been eager to play with Visual Studio Orcas, and being wise about it, probably downloaded the virtual machine images, instead of the whopping 6GB DVD installers. If Virtual Server is used, no doubt many will be faced with the following error
The parent virtual hard disk "E:\VPC\TimeBombedBase\Base01.vhd" for the differencing virtual hard disk "E:\downloads\orcas\OrcasBeta1VSTS.vhd" does not exist. Please reconnect the differencing virtual hard disk to the correct parent virtual hard disk.
Microsoft based their releases on a base disk image, so one has to obtain that as well. The thing was I did not know how to alter the path of the parent disk so it could be relocated to a more convenient drive of my choice. I ended up duplicating that path on my server. Recently I discovered from discussions why I never saw this piece of data in the virtual machine's (vmc) properties - it is embedded in the disk file (vhd) itself.
In order to alter this path, goto to the Virtual Disks > Inspect section from Virtual Server's Master Status web page. Specify the path of the differencing vhd disk, and there will be the option Parent virtual hard disk(s) that is modifiable. No more corny directory names.
