' VirtualBox lets users create virtual machines in which they can install their operating system of choice. The solution is similar to those advertised and sold by VMware (VMware Fusion), or Parallels (Parallels Desktop). The latest version of the software comes with the usual laundry of bug fixes and tweaks, including a ﬁxed problem starting headless VMs without a graphical session in Snow Leopard.
Unlike Parallels Desktop or VMware Fusion, VirtualBox is free to download and use for anyone packing the necessary hardware. The software is a feature-rich, high-performance product for enterprise customers. Available as Open Source Software, VirtualBox is licensed under the terms of the GNU General Public License (GPL). In addition to the aforementioned bug fix, VirualBox 3.0.8 includes the following changes (highlights): VMM: ﬁxed a recompiler triple fault guru meditation (VT-x & AMD-V only);
VMM: ﬁxed hang after guest state restore (AMD-V, 32 bits Windows guest and IO-APIC enabled only);
VMM: ﬁxed paging issue with OS/2 guests;
VMM: ﬁxed guru meditation in rare cases (2.0 regression; software virtualization only);
VMM: ﬁxed rare paging problem with AMD-V;
VMM: ﬁxed release assertion during state restore when using the Sound Blaster 16 emulation;
Security: ﬁxed vulnerability that allowed to execute commands with root privileges;
X11-based hosts: support additional function keys on Sun keyboards;
Mac OS X hosts (Snow Leopard): ﬁxed problem starting headless VMs without a graphical session;
Mac OS X hosts: ﬁxed problem listing host-only adapter names with trailing garbage (attached VMs won’t start);
USB: ﬁxed potential crash when unplugging USB2 devices.
