VirtualBox is a general-purpose full virtualizer for x86 hardware. The software has been targeted for server, desktop and embedded usage. VirtualBox is now the only professional-quality virtualization solution, which is also Open Source Software.
VirtualBox Features:
VirtualBox has an extremely modular design coupled with well-defined internal programming interfaces and a client/server design. The advantage of this is that it makes it easy to control from several interfaces simultaneously. For example, you can start a virtual machine in a typical virtual machine GUI and then control that machine from the command line, or even remotely.
VirtualBox also comes with a full SDK: even though it is Open Source Software, you don’t have to hack the source to write a new interface for VirtualBox.
Virtual machine descriptions in XML. The configuration settings of virtual machines are stored completely in XML and are independent of the local machines. Virtual machine definitions can therefore be ported easily to other computers.
The following changes have been made in this update.
VMM: fixed an occasional Guru Meditation (Mac OS X hosts only)
VMM: fixed a rare condition that would fail to invalidate guest TLB entries or would invalidate them when not required (Windows hosts only)
VMM: fixed a VERR_NOT_SUPPORTED Guru Meditation seen with certain guests, e.g. OpenServer 5.0.7
VMM: more fixes for MSR emulation on certain hardware
GUI: fixed mouse positioning with mouse integration disabled and multiple guest screens (Windows hosts only)
GUI: fixed crash in VM manager
GUI: fixed crash under rare conditions on entering/exiting fullscreen/seamless mode
Shared Clipboard: don’t stop working after taking a snapshot
AHCI: fixed a crash under rare circumstances
API: fixed a hang during VM shutdown under rare conditions
NAT: fixed generation of malformed ICMP error datagrams (4.3.10 regression)
NAT: fixed potential crash in DNS proxy
NAT Network: don’t drop port forwarding rules after some time
NAT: fixed ARP cache corruption and network loss in Windows guest caused by iSCSI service activity
USB: improved check if a storage device is currently mounted to the host when the device is about to be attached to the VM (Mac OS X hosts only)
3D support: several fixes, including better support for Ubuntu 14.04
VRDP: fixed a potential crash on client disconnect
VBoxSVC: fixed a race when a new client is started a few seconds after the last client terminated (Windows hosts only)
VBoxSVC: fixed VirtualBox.xml registry corruption after VM renaming
VBoxSVC: fixed a potential crash caused by incorrect USB device filter (Mac OS X hosts only)
Windows hosts: partly support 32-bit COM on 64-bit systems
Windows host installer: implemented merge module (msm) support
Linux hosts: fixed dependency of boot script on older Debian systems
Linux guests: fix symbolic link to shared folder helper
Linux Additions: don’t crash VBoxService during guest execute for users without a password
Linux Additions: fixed a bug in guest execution where the guest process terminated with VERR_INTERRUPTED to the host
