NEW VERSION RELEASED - v1.20 (see
root message for download link).
Please note that I've released a new version of my CloneVDI tool (v1.20). This new version adds read support for VHD files. The release notes have been updated to reflect this. This release also includes a
very minor bugfix: under certain circumstances a zero length temp file was being left behind.
VHD support should be regarded as experimental. I don't have many VHDs to play with, which limited my test capability.
And just to be sure that everyone knows: converting a VHD to a VDI does not guarantee that it will run under VirtualBox. In the worst case you have Windows guest in VHD form that runs happily under Virtual PC, Virtual Server, Win 7 etc: these VM environments do not emulate the same hardware as VBox does, so when you move this VHD over to VirtualBox (whether or not you convert it to a VDI), then the guest will see a lot of hardware changes and may complain about them. Complaints may range from BSOD on startup, or Windows prompting you to reactivate.
These issues have nothing to do with the VHD to VDI conversion.
