I've had a little problem with *bsd based distros, specifically, FreeNAS and pfSense. When booting the VM, both behave the same and shutdown. With both, it's before I get to the install option, the console freezes (freezes the browser too, both Firefox 8 and Chromium, on Fedora 16 and Linux Mint 9) and the VM will stop. I have changed some of the configuration around (kernel type, amount of cores/cpu's). I don't have these issues with Linux based distros, just seems to be the BSD based ones. Any idea or thing I should check?
