VmSimple¶

public class VmSimple implements Vm ¶

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

Constructors¶

VmSimple¶

public VmSimple(int id, long mipsCapacity, long numberOfPes)¶

Creates a Vm 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 being instantiated, 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)

VmSimple¶

public VmSimple(long mipsCapacity, long numberOfPes)¶

Creates a Vm 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 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` numberOfPes – amount of `Pe` (CPU cores)

VmSimple¶

public VmSimple(int id, double mipsCapacity, long numberOfPes)¶

Creates a Vm 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 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.

Parameters:	id – unique ID of the VM mipsCapacity – the mips capacity of each Vm `Pe` numberOfPes – amount of `Pe` (CPU cores)
