Ah right. I don't use Hyper-V because I want to be able to use USB devices under Linux. I've had a lot more problems under Hyper-V than I have with VirtualBox. Both can't be installed side by side, either, you'd have to remove the boot flag or uninstall Hyper-V before you can use VirtualBox.

VirtualBox also does clipboard and file sharing, but only with the Guest Additions (only tested under a recent Ubuntu).
