is virtual box GPL??? wow, didnt know that! Ive been fighting with kvm for months, just because I have a new Intel chip that supports hardware virtualisation. I used to use VMware which worked like a dream, but it was proprietary. That is the only reason ive been trying to use kvm. If there is a 64bit version of virtualbox and it is gpl, then im changing over right this minute! kvm performance still sucks on an intel core2duo 7200 with 2GB ram. using fiesty 64bit.
