/**
 * This command represents physical view of how a VPC is laid out on the physical infrastructure. Contains information:
 *   - on which hypervisor hosts VPC spans (host running at least one VM from the VPC)
 *   - information of tiers, so we can figure how one VM can talk to a different VM in same tier or different tier
 *   - information on all the VM's in the VPC.
 *   - information of NIC's of each VM in the VPC
