public class VmSimple
extends VmAbstract

Implements the basic features of a Virtual Machine (VM), which runs inside a Host that may be shared among other VMs. It processes Cloudlets (applications). This processing happens according to a policy, defined by the CloudletScheduler. Each VM has an owner/user represented by a DatacenterBroker, which can submit cloudlets to the VM to execute them.

Since:

CloudSim Toolkit 1.0

Constructor Details

VmSimple

public VmSimple(Vm sourceVm)

A copy constructor that creates a VM based on the configuration of another one. The created VM will have the same MIPS capacity, number of PEs, BW, RAM and size of the given VM, but a default CloudletScheduler and no DatacenterBroker.

Parameters:

sourceVm - the VM to be cloned

See Also:

• VmSimple(double, long)

VmSimple

public VmSimple(double mipsCapacity,
 long pesNumber)

Creates a Vm with 1024 MEGA of RAM, 100 Megabits/s of Bandwidth and 1024 MEGA of Storage Size. To change these values, use the respective setters. While the Vm is being instantiated, 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.

NOTE: The Vm will use a CloudletSchedulerTimeShared by default. If you need to change that, just call VmAbstract.setCloudletScheduler(CloudletScheduler).

Parameters:

mipsCapacity - the mips capacity of each Vm Pe

pesNumber - amount of Pe (CPU cores)

See Also:

• VmAbstract.setRam(long)
• VmAbstract.setBw(long)
• VmAbstract.setStorage(SimpleStorage)
• VmAbstract.setDefaultRamCapacity(long)
• VmAbstract.setDefaultBwCapacity(long)
• VmAbstract.setDefaultStorageCapacity(long)

VmSimple

public VmSimple(double mipsCapacity,
 long pesNumber,
 CloudletScheduler cloudletScheduler)

Creates a Vm with 1024 MEGA of RAM, 100 Megabits/s of Bandwidth and 1024 MEGA of Storage Size. To change these values, use the respective setters. While the Vm is being instantiated, 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

pesNumber - amount of Pe (CPU cores)

See Also:

• VmAbstract.setRam(long)
• VmAbstract.setBw(long)
• VmAbstract.setStorage(SimpleStorage)
• VmAbstract.setDefaultRamCapacity(long)
• VmAbstract.setDefaultBwCapacity(long)
• VmAbstract.setDefaultStorageCapacity(long)

VmSimple

public VmSimple(long id,
 double mipsCapacity,
 long pesNumber)

Creates a Vm with 1024 MEGA of RAM, 100 Megabits/s of Bandwidth and 1024 MEGA of Storage Size.

To change these values, use the respective setters. While the Vm is being instantiated, such values can be changed freely.

It receives the amount of MIPS as a double value but converts it internally to a long. The method is just provided as a handy-way to create a Vm using a double value for MIPS that usually is generated from some computations.

NOTE: The Vm will use a CloudletSchedulerTimeShared by default. If you need to change that, just call VmAbstract.setCloudletScheduler(CloudletScheduler).

Parameters:

id - unique ID of the VM

mipsCapacity - the mips capacity of each Vm Pe

pesNumber - amount of Pe (CPU cores)

See Also:

• VmAbstract.setRam(long)
• VmAbstract.setBw(long)
• VmAbstract.setStorage(SimpleStorage)
• VmAbstract.setDefaultRamCapacity(long)
• VmAbstract.setDefaultBwCapacity(long)
• VmAbstract.setDefaultStorageCapacity(long)

VmSimple

public VmSimple(long id,
 long mipsCapacity,
 long pesNumber)

Creates a Vm with 1024 MEGA of RAM, 100 Megabits/s of Bandwidth and 1024 MEGA of Storage Size.

To change these values, use the respective setters. While the Vm is being instantiated, such values can be changed freely.

NOTE: The Vm will use a CloudletSchedulerTimeShared by default. If you need to change that, just call VmAbstract.setCloudletScheduler(CloudletScheduler).

Parameters:

id - unique ID of the VM

mipsCapacity - the mips capacity of each Vm Pe

pesNumber - amount of Pe (CPU cores)

• VmAbstract.setRam(long)
• VmAbstract.setBw(long)
• VmAbstract.setStorage(SimpleStorage)
• VmAbstract.setDefaultRamCapacity(long)
• VmAbstract.setDefaultBwCapacity(long)
• VmAbstract.setDefaultStorageCapacity(long)
