My research is in virtualized infrastructure domain. I aim at minimizing electricity consumption while improving application performance. To achieve the first goal, I work both at the entire datacenter level (by providing better VM placement strategies) and at the physical machine level (by providing better power management policies). Concerning the second goal, I work both at the VM monitor level (for minimizing its overhead) and at the VM's operating system (OS) level (for making it aware of the fact that it is virtualized).
In this talk I present two contributions of my research team, one for each objective.
The first contribution presents Drowsy-DC, a novel way to reduce data center power consumption inspired by smartphones.
The second contribution presents XPV (eXtended Para-Virtualization), a new principle for well virtualizing NUMA machines.
