The massive amount of resources found in datacenters makes it possible to host a large range of applications. Virtualizing these applications allows to consolidate them on servers, reducing runtime costs. Nevertheless, applications expect dependable infrastructures that support their SLA requirements. SLAs are however specific to each application and current schedulers are designed as non-extensible systems with a limited support for SLA. BtrPlace is a flexible Virtual Machine scheduler. It can be customized by the application or the datacenter administrators to support new SLAs, then to keep the datacenter attractive.
