BigBlueButton Virtual Machine
Prerequisites: VMWare Player/Workstation for Windows or Unix VM
Fusion for Mac A DHCP Server to get an IP address on boot
The second point is key: the VM must be able to connect to the
internet to update from packages. If it does not acquire an IP
address, it won't be able to finish the setup of BigBlueButton.

BigBlueButton on Ubuntu

10.04 32-bit or 64-bit server 2 GB of memory Root access to the
server 5G of free disk space Port 80 is not in use by other
applications
Note: BigBlueButton uses nginx, which listens on port 80 for
http access and tunneling. If you have apache already running on
your server, then you'll need to configure apache to listen on a
different port.
