Sun xVM VirtualBox 1.6
What is Sun xVM VirtualBox?
VirtualBox is an absolutely free virtualization product for x86 platform. It supports both 32bit and 64bit architectures and can be used in both server and desktop virtualization.
VirtualBox supports a standard set of features, including the following:
- Unique design – modular and lightweight
- All VM configuration is stored in XML files
- Solaris, Windows and Linux are supported as both host and guest OSes, Mac OS X is supported as host OS.
- Performance: Guest software to optimize the guest VM performance for Linux and Windows
- Networking: Flexible virtual networking (you can even to PXE boot over NAT)
- Storage: SATA support
- Storage: you can use VMware-created disk images (VMDK files)
- Shared folders – seamlessly transfer files between host OS and guest VMs
What's new in VirtualBox 1.6
Obviously, you'll notice that VirtualBox now looks like a Sun product – colors have gone through subtle changes which reflect Sun's elements of design.
Feature-wise, here's what's new in this major update:
- Solaris and Mac OS X host support
- Seamless windowing for Linux and Solaris guests
- Guest Additions for Solaris
- A webservice API
- SATA hard disk (AHCI) controller
- Experimental Physical Address Extension (PAE) support
Apart from this, I really like many other improvements:
- VMM: reduced host CPU load of idle guests
- VMM: many ﬁxes for VT-x/SVM hardware-supported virtualization
- USB: ﬁxed problems with USB 2.0 devices
- NAT: improved builtin DHCP server (implemented DHCPNAK response)
- NAT: port forwarding stopped when restoring the VM from a saved state
- NAT: make subnet conﬁgurable
- Storage: better write optimization, prevent images from growing unnecessarily.
- Shared Folders: many bugﬁxes to improve stability (I'd love to see it fixed cause it was unusable in 1.5 on my 64-bit Ubuntu Gutsy)
- Linux additions: several ﬁxes, experimental support for RandR 1.2
- Linux additions: compatibility ﬁxes with Linux 2.6.25

I've already downloaded it and will definitely give it a try on my home PC. One thing I'm really interested in is double-checking whether there's any tweaking to get VMware Server 2b2 and VirtualBox co-exist in the same Ubuntu Hardy environment.
