VirtualBox is an x86 virtualization software package, originally crted by software company innotek GmbH, purchased by Sun Microsystems, and now developed by Corporation. Within in this, we can run another OS which may be Mac or linux or apart from the existing OS.
VirtualBox Supported guest operating systems include NetBSD, , Linux, DragonFlyBSD, FreeBSD, OpenBSD, OS/2 Warp, Solaris, OpenSolaris, Haiku, Syllable, RctOS, SkyOS, and Mac OS X.

* VMM: large page and monitoring fixes for live snapshots
* GUI: fixed error message when trying to exceed the maximum of host network interfaces
* GUI: fixed saving of changes to the metadata of an existing snapshot
* GUI: fixed rare crash on X11 hosts
* GUI: when selecting a shared folder, start the file dialog in the users home directory
