This is a post to poll the interest, if any, for making ZeroShell available as a Microsoft virtualization technology compatible machine. ZeroShell is already offered as a VMWare compatible VM. It would be possible to convert the VMWare virtual machine to a MS virtual machine, but this is a comlicated and time consuming operation that would have to be repeated each time ZeroShell is updated.
The VHD format used by all Microsoft virutalization software is an open specification which can be used by anybody, roalty free. There are no restrictions on the usage of the format. A lot of third-party utilities, eg. WinImage, already support VHD. Microsoft Virtual PC and Virtual Server are also free applications.
The VHD specification is available here:
