The Xen scheduler is a complex piece of code responsible for scheduling guest virtual machines and managing platform power. What if this complexity could be avoided by reusing the scheduler in a domU instead? This talk is a case study that discusses the benefits and costs of a scheduler-less Xen, in particular its effect on power, performance, emulation, and PCI passthrough. This study is based on the open-source research implementation of the Xen PV interface in the MicroV hypervisor. The goal of this talk to raise awareness of this alternative architecture and to start a discussion on the possibility of bringing this alternative to upstream Xen.
