Virtual machines on linux

VirtualBox OSE

• Free
• Works
• Have to shut VM down to change any settings
• Command line access to read settings:
• VBoxManage list vms
• VBoxManage showvminfo [vm name]
• Can use NAT and port forwarding to access locally when on wifi
• Embiggening a disk is tedious

VMWare

• Very big and heavy
• Client is free
• Software to create VMs is paid
