L4Ka Virtual Machine Technology

We research new technologies for improving the virtual machine experience, addressing microkernels, hypervisors, the performance of running commodity operating systems in virtual machines, techniques for easily accomplishing virtualization, and the application of virtual machines for solving problems.

Projects

Pre-virtualization with Compiler Afterburning
We are developing automation technology for virtualizing operating systems. We enable a single guest OS binary to execute on a variety of hypervisors, and on raw hardware, with the performance of para-virtualization.

Unmodified reuse of device drivers
New operating systems need access to devices, yet the cost of developing the device drivers is dramatic. We developed a technique to reuse pre-existing device drivers, unmodified.

Multiprocessor scalability
A virtual machine environment provides the benefits of flexibly scheduling concurrent virtual machines. We show how to maintain multiprocessor performance in the virtual machine environment.

L4Ka virtual machine environment
For our experiments and research, we are developing light infrastucture to run virtual machines on the L4Ka::Pistachio microkernel.

BurnNT
BurnNT is a project to develop a virtual machine environment that runs as a normal Windows NT application. It hosts pre-virtualized guest kernels.
