The question describes well what I need but here are some more details about the circumstances.
With Parallels Desktop 4 running under Linux, I have a number of Windows 7 Virtual Machines. Sadly, Parallels has not been upgraded for a while, so I am trying some other VMS and VirtualBox was highly recommended. Particularly, it is provided with the OpenSUSE Linux distribution. This will avoid the problem and allow me to keep up to date with the latest OpenSUSE.
So my question is, how can I convert a Parallels VM into a Virtual Box one?
Best Answer
VirtualBox can use Parallels (.hdd) disks in simple-format without conversion. If the disk does not use the simple format, it must be converted first using the Parallels Image Tool.
But I would uninstall Parallels Tools first (if you have it installed on the VM) and make a backup copy of the VM. Then create a new VirtualBox machine, matching the CPU and memory settings as closely as you can to the Parallels machine.
You may also refer to this article on migration, although it is a bit old and recommends using VMWare Converter, which I would avoid if you can.
