Home / What is VM in CloudSim
Generally, the virtual machines are abbreviated as VM and they are the software packages used to emulate the architecture of physical machine. All the VM are implemented through the host and it is deployed to execute the applications.
In addition, all the VM are capable to run various cloudlets and while scheduling all the cloudlets on the CPU core through CloudletScheduler.
For your reference, we have highlighted the code for the creation of VM in the following.
package cloudreports.TaskPriority;
import java.util.ArrayList;
import
org.cloudbus.cloudsim.CloudletSchedulerTimeShared;
import org.cloudbus.cloudsim.Vm;;
public class VmsCreator {
public ArrayList
createRequiredVms(int reqVms, int brokerId){
ArrayList vmlist = new ArrayList();
int vmid = 0;
int mips = 1000;
long size = 10000; //image size (MB)
int ram = 512; //vm memory (MB)
long bw = 1000;
int pesNumber = 1; //number of cpus
String vmm = "Xen"; //VMM name
for(vmid=0;vmid
vmlist.add(new Vm(vmid, brokerId, mips, pesNumber, ram, bw,
size, vmm, new CloudletSchedulerTimeShared()));
}
return vmlist;
}
}
Finally, we have provided the acquired result of performing the VM placement process in CloudSim simulator.
In sum, we hope that we have provided the enough knowledge about the functions of VM in CloudSim. Reach us to acquire more.
I really appreciate your project development team. Since, your source codes are very easy to understand and execute it. Thank you!

You’re amazing and great working with you! I am totally satisfied with your paper writing. Keep up the best service for scholars!
- Lewis
Thank you so much for my project support and you guys are well done in project explanation. I get a clear vision about it.
- Eliza
You’ve been so helpful because my project is based on the AWS and HDFS integration. Before my commitment with you, I’ve a lot of fear, but you people rocked on my project.
- Henry
Your project development is good and you made it so simple. Especially, codes are very new and running without any error.
- Frank
You exactly did my project according to my demand. I tried many services, but I get the correct result from you. So surely I will keep working with you!
