Virtual machine (VM) placement is the current day research topic in cloud computing area. In order to solve the problem of imposing location constraints on VMs to meet their requirements in the process of VM placement, the location-constrained VM placement (LCVP) algorithm is proposed in this paper. In LCVP, each VM can only be placed onto one of the specified candidate physical machines (PMs) with enough computing resources and there must be sufficient bandwidth between the selected PMs to meet the communication requirement of the corresponding VMs. Simulation results show that LCVP is feasible and outperforms other benchmark algorithms in terms of computation time and blocking probability.

位置受限虚拟机放置 (LCVP) 算法

虚拟机（VM）放置是当前云计算领域的研究课题。为了解决VM放置过程中对VM施加位置约束以满足其需求的问题，本文提出了位置约束VM放置（LCVP）算法。在 LCVP 中，每个 VM 只能放置在具有足够计算资源的指定候选物理机 (PM) 上，并且所选 PM 之间必须有足够的带宽以满足相应 VM 的通信需求。仿真结果表明，LCVP 是可行的，并且在计算时间和阻塞概率方面优于其他基准算法。
