As a loyal VirtualBox user I opted for VDI rather than VHD, but now I must convert. So here's what I did:
- Uninstall VBox Guest Additions from the VM
- Shut the VM down (don't save the state).
- Remove the VDI from the Virtual Media Manager in Virtual box before running the command below
- Run the following command using Run As Administrator by right-clicking on the command prompt (from the VBox Install directory unless you've set the PATH variable): VBoxManage clonehd e:\SP2013DEV.vdi c:\SP2013DEVaz.vhd --format VHD
In the above command the first file is the source VDI the second is the destination VHD.
- Wait for the magic to happen it should take a while since VMs with SP on them are pretty big. Going from one drive to another should help a bit.
- Upload to Azure and config a new VM to use that VHD.
I ran into a hiccup in that it appears my vbox installation got messed up during an upgrade and kept telling me that VBoxManage was not a vaild win32 application because it was a zero byte file. Reinstalling VBox did the trick.
I may go to just configuring straight in Azure from now on. I do like the option of building locally then uploading, but I will probably just start with the VHD format from now on since conversion is really just an extra step if you plan on going to Azure.
