Virtual Server 2005 R2 SP1 Beta 2 includes ‘vhdmount’ – a tool to allow you to mount a virtual hard disk directly on your host operating system. While vhdmount is provided as a command line tool – a very small amount of work will allow you to mount VHDs by just double clicking on them. By creating a .reg file with the following contents:
Windows Registry Editor Version 5.00
@=””C:\Program Files\Microsoft Virtual Server\Vhdmount\vhdmount.exe” /u “%1″”
@=””C:\Program Files\Microsoft Virtual Server\Vhdmount\vhdmount.exe” /p “%1″”
And then double clicking on the .reg file (to load it into your registry) you will be able to double click a VHD to mount it, and right click on it to dismount it.
