Disconnecting Virtual NICs

Before you customize the guest network, you should disconnect the virtual NICs to quiesce network traffic during the operation. Disconnecting virtual NICs is a key step in the instant clone process.
You can disconnect a virtual NIC in one of these ways:
  • In the
    spec
     parameter to the
    InstantClone_Task
     method you can specify that the virtual NIC should be disconnected during the instant clone operation. This way leaves the NIC in the source virtual machine active immediately after the clone operation, while the NIC in the clone is idle and ready for customization.
  • In the
    spec
     parameter to the
    ReconfigVM_Task
     method you can change the connection state of a virtual NIC. This way is available either with or without an instant clone operation.

Disconnecting a Virtual NIC with InstantClone_Task

To disconnect a virtual NIC during an instant clone operation, prepare a
VirtualMachineInstantCloneSpec
 data object that specifies the device should be in the disconnected state after the clone operation completes. You pass the clone specification in the
spec
 parameter of
InstantClone_Task
. Assign a value of
disconnect
 to the property
spec.location.deviceChange[].device.connectable.migrateConnect
.

Disconnecting a Virtual NIC with ReconfigVM_Task

To disconnect a virtual NIC by reconfiguring the virtual machine, prepare a
VirtualMachineConfigSpec
 data object that specifies a disconnected virtual NIC. You pass the config specification in the
spec
 parameter of the
ReconfigVM_Task
 method. Assign a value of
False
 to the property
spec.deviceChange[].device.connectable.connected
.
