> VirtualBox is currently free, although now that Oracle has bought out Sun,
things may change. But it works well, and it is stable for me.

The *VirtualBox Open Source Edition (OSE)* is free
software<http://en.wikipedia.org/wiki/Free_software>released under the
GNU
General Public License<http://en.wikipedia.org/wiki/GNU_General_Public_License>(GPL),
from which some closed-source features are missing.

This version cannot be closed again, and will remain in the public domain
forever.
Refer to http://en.wikipedia.org/wiki/Virtualbox#Licensing

Currently Sun deploys the full VirtualBox package free for personal use.
This of course can change in the future.
