Query: Minimizing Total Busy Time with Application to Energy-efficient
  Scheduling of Virtual Machines in IaaS clouds   Infrastructure-as-a-Service (IaaS) clouds have become more popular enabling
users to run applications under virtual machines. Energy efficiency for IaaS
clouds is still challenge. This paper investigates the energy-efficient
scheduling problems of virtual machines (VMs) onto physical machines (PMs) in
IaaS clouds along characteristics: multiple resources, fixed intervals and
non-preemption of virtual machines. The scheduling problems are NP-hard. Most
of existing works on VM placement reduce the total energy consumption by using
the minimum number of active physical machines. There, however, are cases using
the minimum number of physical machines results in longer the total busy time
of the physical machines. For the scheduling problems, minimizing the total
energy consumption of all physical machines is equivalent to minimizing total
busy time of all physical machines. In this paper, we propose an scheduling
algorithm, denoted as EMinTRE-LFT, for minimizing the total energy consumption
of physical machines in the scheduling problems. Our extensive simulations
using parallel workload models in Parallel Workload Archive show that the
proposed algorithm has the least total energy consumption compared to the
state-of-the art algorithms.
