摘要： A method for restarting a virtual machine in a virtual computing system having a plurality of hosts and a resource scheduler for the plurality of hosts includes writing a placement request for the virtual machine to a shared channel that is accessible by the resource scheduler. The method further includes reading a placement result from the shared channel, wherein the placement result is generated by the resource scheduler responsive to the placement request; and restarting the virtual machine in accordance with the placement result.

摘要： In one embodiment, a method for placing virtual machines in a collection is provided. A plurality of equivalence sets of hosts is determined prior to placing virtual machines in the collection. The hosts in an equivalence set of hosts are considered similar. An equivalence set of hosts in the plurality of equivalence sets is selected to place the virtual machines in the collection. The method then places at least a portion of the virtual machines in the collection on one or more hosts in the selected equivalence set of hosts.

摘要： In one embodiment, a method attempts, by a computing device, to determine a placement of a set of virtual machines on available hosts upon failure of a host. The placement considers the set of virtual machines as being not powered on any of the available hosts. The method further determines, by the computing device, a placed list of virtual machines in the set of virtual machines as a recommendation to power on to the available hosts. The determination of the placed list of virtual machines is used to determine a power off list of virtual machines in the set of virtual machines to power off, wherein virtual machines in the power off list of virtual machines are currently powered on available hosts but were considered to be powered off to determine the placement.

摘要： In one embodiment, a method includes determining an instrumentation action to perform with the software program when a logging statement is encountered during execution of a software program. The instrumentation action is performed by an instrumentation service associated with a logging service and the execution of the software program is monitored based on the instrumentation action being performed.
