Vbox is just as fast as Xen for most applications give or take a little depending on what you're doing. About the only place Xen can beat out Vbox is with in networking performance with a guest using the virtio driver, however since I've not tested the newer Vbox which is supposed to better performance there. It's pretty hard to get accurate meaningful benchmarks across a variety of hosts/guests/usage styles, but generally speaking Xen, KVM, and Vbox are in the same performance league despite the differences in hypervisors(Vbox and KVM are fairly similar here). VBox guests may also have significantly better IO performance. Xen's advantage now days lies in it's pci-pass-through support and all the tools built for using/managing it. I think KVM may have pci pass-through support too, but haven't messed with it. A lot of the tools support is more abstracted as well with things like libvirt. I like Vbox on FreeBSD for several reasons, but one of the main benefits is using ZVOL's as the storage backend. You get a lot of the ZFS goodies in your VM that way. You can create scripts to automate your functions, everything done in the GUI can be done in the CLI and more. http://www.virtualbox.org/manual/ch08.html -- Adam Vande More
