摘要： A method and system manages memory in a network of virtual machines, including a copy of a master virtual machine (VM) memory system, the copy accessible to a memory server. The method includes determining whether a memory page requested by a clone VM memory system is fetchable from the memory server, the clone VM memory system hosted in a host memory system; if the memory page is fetchable from the memory server, fetching the memory page from the memory server; determining whether there is sufficient space in the host memory system to load the memory page; if there is insufficient space in the host memory system, evicting a selected memory page from the host memory system; and loading the memory page into the host memory system and the clone VM memory system.

摘要： A method and a system for creating a network of virtual machines in a communication network including a head node virtual machine (VM) for distribution and processing of a workload. The method comprises creating the head node VM hosted at a server computer, the head node VM specifying the workload, the workload being assignable into sub-tasks; identifying a pool of hosts for hosting a plurality of replica VMs, each of the pool of hosts comprising a physical computing device; replicating the head node VM at an each one of the plurality of replica VMs; coordinating amongst the plurality of replica VMs to assign at least one workload sub-task to the each one of the plurality of replica VMs; processing the at least one assigned workload sub-tasks at the respective each one of the plurality of replica VMs to provide at least one sub-task result; and receiving the at least one sub-task result at the head node VM.
摘要翻译：一种用于在包括用于分发和处理工作负载的头节点虚拟机（VM）的通信网络中创建虚拟机网络的方法和系统。该方法包括创建在服务器计算机上托管的头节点VM，指定工作负载的头节点VM，可分配到子任务中的工作负载; 识别用于托管多个副本VM的主机池，所述主机池中的每一个包括物理计算设备; 在所述多个复制VM中的每一个复制VM上复制所述头节点VM; 在多个复制VM之间进行协调，以将至少一个工作负载子任务分配给多个复制VM中的每一个; 在所述多个副本VM中的每一个处理所述至少一个所分配的工作负载子任务以提供至少一个子任务结果; 以及在所述头节点VM处接收所述至少一个子任务结果。
