Field Summary

ResourceConstraints	cumulativeRC All VMs in the request should have this much resources in total
ResourceConstraints	queuedRC A single VM should have this much resources allocated to it
Repository	queuedRepo The repository that is storing the VM's virtual appliance.
VirtualMachine[]	queuedVMs The VMs to be placed on a PM
long	receivedTime The time stamp when the VM request has been received by the VM scheduler
Map<String,Object>	schedulingConstraints Data for custom schedulers (e.g., like specific placement requirements - please put me on this machine and this machine only), if null then there is no data.

Constructor Summary

QueueingData(VirtualMachine[] vms, ResourceConstraints rc, Repository vaSource, Map<String,Object> schedulingConstraints, long received)
Instantiates the queueing data object which auto-populates the derivable fields and safeguards all data stored.

Field Detail

queuedVMs

public final VirtualMachine[] queuedVMs

The VMs to be placed on a PM

queuedRC

public final ResourceConstraints queuedRC

A single VM should have this much resources allocated to it

cumulativeRC

public final ResourceConstraints cumulativeRC

All VMs in the request should have this much resources in total

queuedRepo

public final Repository queuedRepo

The repository that is storing the VM's virtual appliance.

schedulingConstraints

public final Map<String,Object> schedulingConstraints

Constructor Detail

QueueingData

public QueueingData(VirtualMachine[] vms,
                    ResourceConstraints rc,
                    Repository vaSource,
                    Map<String,Object> schedulingConstraints,
                    long received)

Instantiates the queueing data object which auto-populates the derivable fields and safeguards all data stored.

Parameters:

vms - the virtual machine set to work on

rc - the resource requirements for a single VM

vaSource - the repository which hosts the virtual appliance required for the instantiation of the VMs

schedulingConstraints - custom scheduler data

received - the timestamp

Method Detail

toString

public String toString()

Provides a user readable single line representation of the queued VMs. Good for debugging and tracing.

Overrides:
