Security of Virtual Machines
... Virtual machines are not physical, which means their theft can take place without physical theft of the host machine. The contents of the virtual disk for each VM are stored as a file by most hypervisors, which allows VMs to be copied and run from other physical machines. Attackers can copy the VM o ...
