| Virtual machine (VM) consolidation has become a common practice in clouds, Grids, and datacenters. While this practice leads to higher CPU utilization, we observe its negative impact on performance of applications in VMs. As more VMs share the same core/CPU, the CPU scheduling latency for each VM increases significantly. On one hand, such increase leads to slower progress of TCP transmissions to the VMs; on another side, increased CPU access latency experienced by each VM translates into longer I/O processing latency perceived by I/O bound applications. To mitigate such negative impact, our group proposed //vFlood//, //vSnoop// and //vSlicer//. vFlood and vSnoop focus on increasing the TCP throughput of VMs. vSlicer solves performance problems of I/O bound applications, which are produced by longer CPU access latency experienced by VMs. Our evaluation results show significant improvements in application-specific performance. | Virtual machine (VM) consolidation has become a common practice in clouds, Grids, and datacenters.
