With technologies such as SDN and NFV pushing the the development of the next generation networks, new paradigms, such as Fog Computing, appeared in the network scene. However, these technologies have been associated with the network infrastructure, such as the datacenter. In order for these technologies to be used, for instance, in a Fog Computing scenario it is necessary to, therefore, study and develop these technologies to form new control and operation mechanisms. So, a Fog Computing scenario composed by resource-constrained devices, typical in these types of situations, was developed, and, a solution proposal is presented. The solution consists in customizing an existent VIM, OpenVIM, to this kind of devices, after the implementation of the solution, where a Raspberry Pi is used to exemplify this type of devices. Tests are done to measure and compare this devices to more powerful ones. The tests are comprised by benchmarks runs, focusing on instantiation times, and power consumption. The results show some drawbacks inherent to this kind of devices when compared to more powerful ones. However, it is possible to see the potential that this kind of devices might have in the near future.
