Exporting a VM to VMWare Fusion
Not the easiest procedure in the world but certainly the most effective, exporting your virtual machine from VirtualBox to VMWare Fusion requires the creation of a special file that can then be adjusted and imported into VMWare Fusion.
With you virtual machine suspended, go to File > Export Appliance to create an industry-standard OVF compliant VM file. This might take a little while to create, depending on how much hard disk space your VM was using.
You will then need to find the OVF file and open it in a text editor. With a raw text version of the OVF file visible, find the term "ovf:format=" and change the following text to read as follows:
Use the text editor's Find tool to look for the "Virtual SystemType" and confirm it reads as either of the following:
<vssd:VirtualSystemType>vmx-07</vssd:VirtualSystemType> (for a esx 4.0)
<vssd:VirtualSystemType>vmx-04</vssd:VirtualSystemType> (for esx 3.5.x and 4.0 hosts)
Finally, find "<rasd:Caption>sound" add the following line above it:
Save the file, and then close.
Once complete, you’re ready to use this OVF file in VMWare Fusion. Visit www.vmware.com/support/developer/ovf/ to download the VMWare OVF Tool – this is a command line utility designed for importing and exporting OVF files.
