3. Threats in virtual environments
3.1 Sources of vulnerability
One of the major benefits of virtualization is the transition from physical servers to virtual equivalents. Dedicated servers become virtualized, and benefit from new features such as hot migration.
Live migration involves migrating a running VM between two physical servers, without interrupting service. Memory, storage and network resources attached to the VM are seamlessly transferred from the original physical server to the destination.
However, VMs indirectly share the same physical resources. New isolation mechanisms must therefore be found to prevent a VM from exploiting one of the hypervisor's interfaces, and to attempt to steal data from co-located VMs. In...
