What Are The Requirements? VirtualBSD is a virtual appliance, which means you will need:
Windows and Linux: VMware Player / Workstation / Server or VirtualBox. Mac OS X: VMware Fusion or VirtualBox. RAM: 1 GB for the virtual machine and possibly at least as much for the host OS (but check this tip to use less). Disk Space: About 8 GB (the VM itself takes nearly 6 GB).
