Recently, the performance of CPUs is improving by the technology of integrating circuits. By this improving, CPUs satisfies the demand which is needed for executing software on the computer. Therefore, CPUs aren’t always used fully. To use CPU more efficiently, the virtualization technology is used in various situations such as Web service, database service, cloud computing service, and so on. In this technology, users can integrate plural VMs (Virtual Machines) on one physical computer. However, when the number of processor cores is less than the number of VMs, the scheduler can’t concurrently allocate the CPU to all VMs. In this situation, each VM is allocated the CPU by the time sharing. Therefore, when all processor cores are allocated to other executions, the executable VM waits for allocating the CPU. This situation becomes the problem when the CPU is needed for real time processing on the VM, which is ready to execute. To solve this problem, we proposed Priority Control Method, which enables us to control allocating the CPU resources for each VM. Moreover, we evaluated the effectiveness of Priority Control Method by using the priority of the process before. However, we didn’t evaluate this method in Fedora 20 that is latest version of Fedora. Moreover, Fedora 20 has cgroups (Control Groups) that is the function of managing resources. Cgroups includes the function for the control of allocating the CPU to each VM.
In this paper, we describe the effectiveness of Priority Control Method with KVM (Kernel-based Virtual Machine), which is one of methods for the virtualization of the computer. Moreover, we describe the evaluation that we tried to control allocating CPU for VMs by using cgroups in KVM.
