    • Techniques for placement of a virtual machine in a computing system. A first request is sent from a pool management subsystem to a placement subsystem. The first request includes specification of available storage capacities of storage systems in a computer network. The placement subsystem automatically determines a target storage system based, at least in part, on the available storage capacities. An identification of the target storage system is received at the pool management subsystem. At least one disk image of the virtual machine is written to the target storage system. Then, a second request is sent to the placement subsystem. The placement subsystem automatically determines a target computer. The latter determination is based, at least in part, on connectivity between the target computer and the target storage system. The virtual machine is installed at the target computer. The techniques facilitate live migration of virtual machines placed thereby.
    • 在计算系统中放置虚拟机的技术。 从池管理子系统向布局子系统发送第一个请求。 第一个请求包括计算机网络中存储系统的可用存储容量的规范。 至少部分地基于可用存储容量,放置子系统自动地确定目标存储系统。 在池管理子系统处接收目标存储系统的标识。 将虚拟机的至少一个磁盘映像写入目标存储系统。 然后,第二个请求被发送到放置子系统。 放置子系统自动确定目标计算机。 后者的确定至少部分地基于目标计算机和目标存储系统之间的连接。 虚拟机安装在目标计算机上。 这些技术有助于虚拟机的实时迁移。
