摘要： Sessions states within virtual machine (VM) environments are maintained. Each VM environment hosts a guest operating system (OS) and one or more application programs running. The guest OS and the application computer programs of each VM environment constitute a session. A connection broker maintains a state machine as to states of the sessions and permits transitions among the states in response to messages, commands, and internal decisions. Different types of agents may send the messages, and the commands. The states of the sessions may include a pending state and a number of other states. The pending state is an interim state that indicates a session is being transitioned from one of the other states to another of the other states. These other states may include an offline state, an online-down state, an online-up state, a suspended state, an active state, an idle state, a disconnected state, and a failed state.

摘要： Virtual machines are managed on the basis of data obtained from a management information database of a network switch having a plurality of Ethernet links coupled to compute nodes running a plurality of virtual machines. A management entity, such as a provisioning manager, determines the amount of network bandwidth being utilized through each of the Ethernet links. Accordingly, an additional virtual machine may be provisioned to the compute node that is coupled to an Ethernet link identified as having the greatest amount of unutilized network bandwidth.

摘要： Method and computer program for managing the network response times experienced by virtual machines. Traffic is routed within an Ethernet network through a network switch according to IP addresses identified within Ethernet frames. A plurality of compute nodes are each coupled to the network switch via a separate Ethernet link. A response time is determined for each virtual machine running on the compute nodes, wherein the response time for a particular virtual machine is the difference between a time stamp in a TCP/IP Request message and a time stamp in a TCP/IP Response message for an IP address assigned to the particular virtual machine. The particular virtual machine may then be migrated to a target compute node in response to a particular one of the virtual machines on a particular one of the compute nodes having a response time that exceeds a response time setpoint.

摘要： A system includes a number of server computing devices and a management server computing device. Each server computing device has a virtual host computer program running thereon to support one or more virtual machine computer programs. Each virtual machine computer program is able to execute an instance of an operating system on which application computer programs are executable. The management server computing device monitors the server computing devices, and causes the virtual machine computer programs supported by the virtual host computer program of a first server computing device to dynamically migrate to the virtual host computer program of a second server computing device, upon one or more conditions being satisfied. The conditions may include the first server being predicted as failure prone, the first server consuming power less than a threshold, and the first server having resource utilization less than a threshold.
