Abstract
We describe how a virtual machine VM owner can increase visibility about how a VM and its data are stored and processed in the cloud. We present 'VMInformant', a monitoring system which can keep the user informed about events that take place on their VM both inside the VM and via calls made through a hypervisor. A taxonomy of VM security-related events is presented, along with performance overheads associated with monitoring such events using CPU and I/O intensive benchmarks. We argue that having this level of transparency is essential to improve trust between a cloud consumer and provider.
