Yesterday I used Virtualbox for the first time, to create a Beowulf cluster.
Today, I am migrating my Ubuntu VM from VMWare Player to VirtualBox.
This is dead simple with a linux client:
- Copy your VMware image to your Virtualbox VM location
- Open up VirtualBox and go File->Virtual Media Manager
- Add the .vmdk file as a hard disk in the Virtual Media Manager
- Create a new VM, using the hard disk you copied as the disk.
That's it! Could it be simplier?
For Windows, things are a bit more difficult. See this link for more details.
