Virtual Machine Manager

This paper presents an optimization approach for the COW VBD in virtual machine monitor(VMM),which can improve the access performance of COW disks and can make many small-sized COW disk images to reduce the cost of VM deployment over the network.

文中为虚拟机管理器中的COW虚拟块设备设计了一种优化方法,能够提高COW磁盘的访问性能以及生成多个小尺寸的COW磁盘映像文件,以降低通过网络部署虚拟机的开销。
