Since vmware is not working anymore, it's been a long time for waiting VirtualBox in FreeBSD!
If you are using 7.2-RELEASE, just update your ports and install emulators/virtualbox. There are some
problems but generally it works very well. I am using virtualbox-2.2.51.r20457_3.
As you can see, IE8 menu looks broken but I don't know why. It may be related to graphics engine but I can see Youtube HD movies without problem.
Thanks for hard job, ports people!
