This article is part of the Service Provider Foundation Programmers Guide (SPF).

Table of Contents

You can delete a virtual machine from Service Provider Foundation by passing the instance of the virtual machine to the DeleteObject method of the service. When using HTTP, use the DELETE operation with the specific virtual machine identified in the URI.

Tip
Before a virtual machine can be deleted, it must be in a stopped state. To learn how to stop a virtual machine, see Start or Stop a Virtual Machine (SPF).

To delete a virtual machine with .NET

  1. Connect to the Service Provider Foundation VMM service.

  2. Query for a specific SpfVMM.VirtualMachine.

  3. Call the DeleteObject method on the VMM service object reference and pass in the virtual machine reference.

  4. Call the SaveChanges method on the VMM service object reference.

To delete a virtual machine with HTTP

  1. Create a new HTTP DELETE operation.

  2. Set the URL to the appropriate URI of a specific virtual machine: https://server:30005/subscription-id/services/systemcenter/vmm/VirtualMachines(ID=guid'vm-id',StampId=guid'stamp-id')

  3. Add the HTTP headers.

    Specifically, add the x-ms-principal-id header, which can be set to any value.

  4. Create an empty HTTP body.

  5. Submit the HTTP request.

Example

The following example deletes a specific virtual machine.

SpfVMM.VMM vmmService = new SpfVMM.VMM(new Uri("https://wapserver:30005/97FD50F3-1DC0-41B6-A7C0-2B4FF4C3F7E3/services/systemcenter/vmm/"));
vmmService.Credentials = System.Net.CredentialCache.DefaultNetworkCredentials;

var virtualMachine = vmmService.VirtualMachines.Where(vm => vm.ID == new Guid("2fa28d03-8d6d-486b-ae61-9694a2db5d6f")).FirstOrDefault();

if (virtualMachine != null)
{
    vmmService.DeleteObject(virtualMachine);
    vmmService.SaveChanges();
}

The following is an example HTTP request sent to the server:
