Change vm network label

[Nick Wiesmueller]

I'm trying to change the network label of a vm and I cribbed
your(Seba's) code for changing the mac address and made a modification
which I though would work, but doesn't appear to, even though in the
end I get a "Vm successfully reconfigured". What am I doing wrong?

vm_obj=self.server.get_vm_by_name(vm)
if vm_obj:
#Find Virtual Nic device
net_device = None
for dev in vm_obj.properties.config.hardware.device:
if dev._type in ["VirtualE1000", "VirtualE1000e",
"VirtualPCNet32", "VirtualVmxnet"]:
net_device = dev._obj
break

if not net_device:
raise Exception("The vm seems to lack a Virtual Nic")
#Set Nic macAddress to Manual and set address
#net_device.set_element_addressType("Manual")
net_device.DeviceInfo.set_element_label(label)
#Invoke ReconfigVM_Task
request = VI.ReconfigVM_TaskRequestMsg()
_this = request.new__this(vm_obj._mor)
_this.set_attribute_type(vm_obj._mor.get_attribute_type())
request.set_element__this(_this)
spec = request.new_spec()
dev_change = spec.new_deviceChange()
dev_change.set_element_device(net_device)
dev_change.set_element_operation("edit")
spec.set_element_deviceChange([dev_change])
request.set_element_spec(spec)
ret =
self.server._proxy.ReconfigVM_Task(request)._returnval

#Wait for the task to finish
task = VITask(ret, self.server)

status = task.wait_for_state([task.STATE_SUCCESS,
task.STATE_ERROR])
if status == task.STATE_SUCCESS:
print "VM %s successfully reconfigured" % vm
elif status == task.STATE_ERROR:
print "Error reconfiguring vm: %s" % vm,
task.get_error_message()
else:
print "Vm %s not found" % vm

Hi Nick,

   I think I've figured out what's wrong. It seem that there are some properties that can't be changed, they are just informative so they are read-only.

When you change a vm's network label from the vSphere Client, you are actually changing a different property. So, if you want to switch the vm virtual nic to a different network:

replace this line:

net_device.DeviceInfo.set_element_label(label) 

with this:

net_device.Backing.set_element_deviceName(label)

I hope this is what you were looking for.

Best regards,

Sebastian.

Hi Seba,

we are trying to change network label from DVS (N1K) to Standard Switch. Our code did not work, Do you have any idea?

>>> _this.set_attribute_type(vm_object._mor.get_attribute_type())

>>> request.set_element__this(_this)
>>> spec = request.new_spec()
>>> dev_change = spec.new_deviceChange()

>>> dev_change.set_element_device(dev._obj)
>>> dev_change.set_element_operation("edit")
>>> devs_changed = []
>>> devs_changed.append(dev_change)
>>> spec.set_element_deviceChange(devs_changed)
>>> request.set_element_spec(spec)
>>> ret = s._proxy.ReconfigVM_Task(request)._returnval
Traceback (most recent call last):
