A sledgehammer approach to reuse of legacy device drivers

Joshua LeVasseur, Volkmar Uhlig
2004 Proceedings of the 11th workshop on ACM SIGOPS European workshop: beyond the PC - EW11  
We run the unmodified device driver, with its complete original OS, isolated in a virtual machine.  ...  Device drivers account for the majority of an operating system's code base, and reuse of the existing driver infrastructure is a pragmatic requirement of any new OS project.  ...  The other Linux kernels lack direct device access and instead interface with the DD/OS for network services. They each use a specialized network device driver which com-municates with the DD/OS.  ...

On the Performance of Virtualized Infrastructures for Processing Realtime Streaming Data

Kathleen Ericson, Shrideep Pallickara
2012 2012 IEEE Fifth International Conference on Utility and Cloud Computing  
The dominant approach in cloud settings is to provision virtual machines (VMs) rather than provision direct access to the physical machine.  ...  We have done extensive performance benchmarks (using Xen and KVM) the results of which form the basis for our recommendations for the trade-offs involved in these settings.  ...  Since it is fully virtualized, virtual machines (VMs) do not have direct access to I/O interfaces and need to make calls out to the host OS in order to read and write from network and disk interfaces,  ...
