Constructor Details

NetworkVm

public NetworkVm(int id,
 long mipsCapacity,
 int numberOfPes)

Creates a NetworkVm with 1024 MEGA of RAM, 1000 Megabits/s of Bandwidth and 1024 MEGA of Storage Size. To change these values, use the respective setters. While the Vm is not created inside a Host, such values can be changed freely.

Parameters:

id - unique ID of the VM

mipsCapacity - the mips capacity of each Vm Pe

numberOfPes - amount of Pe (CPU cores)

NetworkVm

public NetworkVm(long mipsCapacity,
 int numberOfPes)

Creates a NetworkVm with 1024 MEGA of RAM, 1000 Megabits/s of Bandwidth and 1024 MEGA of Storage Size. To change these values, use the respective setters. While the Vm is not created inside a Host, such values can be changed freely.

It is not defined an id for the Vm. The id is defined when the Vm is submitted to a DatacenterBroker.

Parameters:

mipsCapacity - the mips capacity of each Vm Pe

numberOfPes - amount of Pe (CPU cores)

Method Details

isFree

public boolean isFree()

Indicates if the VM is free or not.

getCloudletList

public List<NetworkCloudlet> getCloudletList()

List of NetworkCloudlet of the VM.

setCloudletList

public void setCloudletList(List<NetworkCloudlet> cloudletList)

getReceivedPacketList

public List<VmPacket> getReceivedPacketList()

List of packets received by the VM.

setReceivedPacketList

public void setReceivedPacketList(List<VmPacket> receivedPacketList)

setFree

public void setFree(boolean free)

getFinishTime

public double getFinishTime()

The time when the VM finishes processing its cloudlets.

setFinishTime

public void setFinishTime(double finishTime)

getHost

public NetworkHost getHost()

Description copied from interface: Vm

Gets the Host where the Vm is or will be placed. To know if the Vm was already created inside this Host, call the Vm.isCreated() method.

Specified by:

getHost in interface Vm

Overrides:

getHost in class VmSimple

Returns:

the Host

See Also:

• Vm.isCreated()

setHost

public Vm setHost(Host host)

Description copied from interface: Vm

Sets the PM that hosts the VM.

Specified by:

setHost in interface Vm

Overrides:

setHost in class VmSimple

Parameters:

host - Host to run the VM

Returns:
