Control Hyper-V VMs with Python

Question

im trying to write a control VMs on a HyperV Server using Python. I start with connecting to the server the HyperV server runs on:

connection = wmi.connect_s         


        

Answer 1

So, I finally found the solution. It was much easier than I thought, but whatever:

1.Connect to your server and get the WMI-object:

connection = wmi.connect_server(server=serverName, namespace=r"root\virtualization", user=username, password=password)
wmiServerConnection = wmi.WMI(wmi=connection)

2.Get the system object and the management service object:

#get object representing VM
vmSystem = wmiServerConnection.Msvm_ComputerSystem(ElementName=VmName)
#get object responsible for VM
vmManagement = wmiServerConnection.Msvm_VirtualSystemManagementService()

3.Get the objects associated with the VM:

#get objects the VM contains
    vmObjects = vmSystem[0].associators(wmi_result_class="Msvm_VirtualSystemSettingData ")

4.Apply the snapshot you want:

for singleVmObject in vmObjects:    
    if(singleVmObject.SettingType == 5 and singleVmObject.ElementName == snapshotName):
        retVal = vmManagement[0].ApplyVirtualSystemSnapshotEx(vmSystem[0].path(), singleVmObject.path())
