An example method to maintain services in a cloned virtual machine (VM) includes detecting a cloning operation of a virtual machine, the cloning operation causing the cloned virtual machine to be generated from a source virtual machine having a first virtual network interface card (VNIC) with a first machine access control (MAC) address, the cloned virtual machine having a second VNIC with a second MAC address unique from the first MAC address, and causing a device identifier associated with the second VNIC of the cloned virtual machine to be changed to match a device identifier associated with the first VNIC of the source virtual machine, the device identifier of the cloned virtual machine being generated by a guest operating system running in the cloned virtual machine upon detection of the presence of the second VNIC with the second MAC address.
