Method Summary

PhasedFuture<AllocationPhase,VirtualMachine>	allocate(Collection<ServerPool> serverPools, AllocationConstraints constraints, List<Listener<AllocationPhase>> listeners) allocate a virtual machine within the provided server pools, notifying of progress all listeners
ServerPoolAllocationStrategy	getServerPoolStrategy(ServerPool serverPool) Returns the server pool allocation strategy for a particular server pool instance.

Method Detail

allocate

PhasedFuture<AllocationPhase,VirtualMachine> allocate(Collection<ServerPool> serverPools,
                                                      AllocationConstraints constraints,
                                                      List<Listener<AllocationPhase>> listeners)
                                                      throws VirtException

allocate a virtual machine within the provided server pools, notifying of progress all listeners

Parameters:

serverPools - the server pools elligible to run the virtual machine

constraints - the virtual machine requested characteristics

listeners - listeners to register before any work is performed

Returns:

a phased future implementation that can be used to monitor progress and get the result of the allocation as VirtualMachine instance.

Throws:

VirtException - if the allocation failed.

getServerPoolStrategy

ServerPoolAllocationStrategy getServerPoolStrategy(ServerPool serverPool)

Returns the server pool allocation strategy for a particular server pool instance.

Parameters:

serverPool - the server pool instance

Returns:

the server pool allocation strategy
