VM placement optimization

[sagana]

in which class we can place the "vm placement optimization" or its already in any class . If it means anbody tell me the clss name that vode is present

Sagana,

You need to implement a vm allocation policy. See the classes: VmAllocationPolicy (http://code.google.com/p/cloudsim/source/browse/trunk/modules/cloudsim/src/main/java/org/cloudbus/cloudsim/VmAllocationPolicy.java), VmAllocationPolicySimple (http://code.google.com/p/cloudsim/source/browse/trunk/modules/cloudsim/src/main/java/org/cloudbus/cloudsim/VmAllocationPolicySimple.java) NetworkVmAllocationPolicy (http://code.google.com/p/cloudsim/source/browse/trunk/modules/cloudsim/src/main/java/org/cloudbus/cloudsim/network/datacenter/NetworkVmAllocationPolicy.java)

It is in Vm allocationpolicy or in its derived classes

Is Power aware best fit decreasing vm placement policy implemented in cloudsim? if yes then in which class?
 thanks and regard.

The Power Aware Best Fit Decreasing(PABFD) policy cannot be found in cloudsim, it is first described in this paper "Energy-aware resource allocation heuristics for efficient management of data centers for cloud computing" .

Best Regards.

then whats this?

protected List<Map<String, Object>> getNewVmPlacement(

List<? extends Vm> vmsToMigrate,

Set<? extends Host> excludedHosts) {

List<Map<String, Object>> migrationMap = new LinkedList<Map<String, Object>>();

PowerVmList.sortByCpuUtilization(vmsToMigrate);

for (Vm vm : vmsToMigrate) {

PowerHost allocatedHost = findHostForVm(vm, excludedHosts);

if (allocatedHost != null) {

allocatedHost.vmCreate(vm);

Log.printLine("VM #" + vm.getId() + " allocated to host #" + allocatedHost.getId());

Map<String, Object> migrate = new HashMap<String, Object>();

migrate.put("vm", vm);

migrate.put("host", allocatedHost);

migrationMap.add(migrate);

}

}

return migrationMap;

Yes, the code is the implementation of VM Placement Pseudo Code of Section 6.3 Algorithm 2(PABFD) in the paper "Energy-aware resource allocation heuristics for efficient management of data centers for cloud computing".

 but in CloudSim the function is called <getNewVmPlacement> instead of <PABFD>, so the searching of "PABFD" is null.

hi pallavi
can you suggest me exact path of Power Aware Best Fit Decreasing(PABFD) policy in cloudsim

Hi
l want to change vm placement method in cloudsim.what class implement vm placement?
tanks alot

Hi n s,

The above code is implemented in PowerVmAllocationPolicyMigrationAbstract.java

thanks,
