Constructor Detail

• VM

  public VM​(Host host,
            java.lang.String name)

  Create a `basic' VM : 1 core and 1GB of RAM.

  Parameters:

  host - Host node

  name - name of the machine

• VM

  public VM​(Host host,
            java.lang.String name,
            int coreAmount)

  Create a VM without useless values (for humans)

  Parameters:

  host - Host node

  name - name of the machine

  coreAmount - the amount of cores of the VM

• VM

  public VM​(Host host,
            java.lang.String name,
            int ramSize,
            int migNetSpeed,
            int dpIntensity)

  Create a VM with 1 core

  Parameters:

  host - Host node

  name - name of the machine

  ramSize - size of the RAM that should be allocated (in MBytes)

  migNetSpeed - (network bandwith allocated for migrations in MB/s, if you don't know put zero ;))

  dpIntensity - (dirty page percentage according to migNetSpeed, [0-100], if you don't know put zero ;))

Method Detail

• all

  public static VM[] all()

  Retrieve the list of all existing VMs

• getVMByName

  public static VM getVMByName​(java.lang.String name)

  Retrieve a VM from its name

• finalize

  protected void finalize()
                   throws java.lang.Throwable

  Overrides:

  finalize in class java.lang.Object

  Throws:

  java.lang.Throwable

• isCreated

  public int isCreated()

  Returns whether the given VM is currently suspended

• isRunning

  public int isRunning()

  Returns whether the given VM is currently running

• isMigrating

  public int isMigrating()

  Returns whether the given VM is currently running

• isSuspended

  public int isSuspended()

  Returns whether the given VM is currently suspended

• getCoreAmount

  public int getCoreAmount()

  Returns the amount of virtual CPUs provided

• setBound

  public void setBound​(double bound)

  Set a CPU bound for a given VM.

  Parameters:

  bound - in flops/s

• start

  public void start()

  start the VM

• shutdown

  public void shutdown()

  Immediately kills all processes within the given VM. No extra delay occurs. If you want to simulate this too, you want to use a MSG_process_sleep()

• destroy

  public void destroy()

  Shutdown and unref the VM.

• migrate

  public void migrate​(Host destination)
               throws HostFailureException

  Change the host on which all processes are running (pre-copy is implemented)

  Throws:

  HostFailureException

• suspend

  public void suspend()

  Immediately suspend the execution of all processes within the given VM No suspension cost occurs. If you want to simulate this too, you want to use a @ref File.write() before or after, depending on the exact semantic of VM suspend to you.

• resume

  public void resume()

  Immediately resumes the execution of all processes within the given VM No resume cost occurs. If you want to simulate this too, you want to use a @ref File.read() before or after, depending on the exact semantic of VM resume to you.
