Add virtual machine migration #32
Description
Given that the simulator now contains a hypervisor implementation, the simulated resource manager should be adapted to be able to migrate them. At this point, this means a simplistic model of instantaneous migrations from one machine to the other, without looking at transfer times.
This includes:
- Researching and selecting a set of migration policies that we want to implement
- Implement these policies in the scheduler
- Support migration of VMs through simple manipulation of the physical properties included within the logical model (i.e. modifying the machine a certain VM has been assigned to)
