Migrate VMWare box to VirtualBox

(from http://ctors.net/2014/07/17/vmware_to_virtualbox)

The instructions below will guide you through the converting process.

VMWare

• Boot the VM
• Uninstall vmware tools
• Shutdown
• Edit VM settings -> remove the HD
• Edit the_machine.vmdk
• change ddb.adapterType from "buslogic" or "lsilogic" to "ide"
• Edit VM settings -> add an HD, type IDE from existing file the_machine.vmdk
• Boot the VM
• Shutdown

Now you can convert the box from VMWare to Open Virtualization Format.

$ ovftool -o the_machine.vmx the_machine.ovf Opening VMX source: the_machine.vmx Opening OVF target: the_machine.ovf Writing OVF package: the_machine.ovf Transfer Completed Completed successfully

VirtualBox

The last step is to import the OFV in VirtualBox and install guest additions.

• File -> import appliance -> the_machine.ovf
