Systems and methods for domain management in a virtualized computing environment are provided. In one embodiment, the method comprises collating advice received from one or more domain advisors connected in the virtualized computing environment; resolving any conflicts among the advice received from said one or more domain advisors; utilizing the collated advice to generate a placement plan comprising a plurality of operations for virtual machines in said virtualized computing environment; and executing the one or more operations in the placement plan, wherein one or more domain handlers may be called to update the virtualized computing environment before, during or after execution of one or more operations from among said plurality of operations in the plan.

Systems and methods for reducing risk of service interruptions for one or more virtual machines (VMs) in a computing environment are provided. The method comprises computing a placement scheme for placing at least one VM on one or more hosts according to a set of placement constraints defined for the VM, wherein the set of placement constraints comprises at least one availability constraint defined for the VM, wherein the availability constraint designates a N resiliency level, wherein N corresponds to number of host failures that may occur before the services provided by the VM are interrupted.

Systems and methods for planning the execution of one or more plans in a virtualized computing environment are provided. In one embodiment, the method comprises computing an order for execution for one or more plans, and the corresponding operations in said one or more plans; validating whether a plan and the corresponding operations for the plan may be successfully executed, prior to executing the plan and the corresponding operations; executing the plan and the corresponding operations, in response to a successful validation; and aborting execution of the plan and the corresponding operations, in response to an unsuccessful validation, wherein the validating process takes into consideration impact of other plans that are previously validated and possible changes in the computing environment since time the plan was computed.

Methods and systems for generating a placement plan for one or more virtual machines (VMs) in a computing environment are provided. The method comprises providing, to a computing system, input parameters comprising a current placement for the one or more VMs on one or more hosts in a computing network; a target placement that assigns at least one of the one or more VMs to at least another host in said one or more hosts; and a set of constraints with which both the current placement and the target placement comply.

Systems and methods for allocating resources to service one or more requests, the method comprising: associating with at least one host from among N hosts, in a computing environment, a first value that reflects a probability that servicing a first request will interfere with operations on the host; selecting M hosts out of the N hosts, wherein the N hosts comprise one or more resources for servicing a first request and wherein at least one of the selected M hosts is determined to be at least as suitable as N−M unselected hosts, for the purpose of servicing the first request; and prior to allocation of resources, updating for at least a first host from among the M hosts the corresponding first value to reflect that servicing the first request may interfere with operations pertaining to other previously received requests that are scheduled to be serviced by the first host.
