// Agent supports multiple type of VMInterfaces

// interface associated with it. Agent also expects a INSTANCE_MSG from
// nova-compute/equivalent to add this port
// DeviceType = VM_ON_TAP, VmiType = INSTANCE
// - VMI for a virtual-machine spawned on VMware ESXi. All virtual-machines
// are connected on a physical-port and VLAN is used to distinguish them
// DeviceType = VM_PHYSICAL_VLAN, VmiType = INTANCE, agent->hypervisor_mode = ESXi
// - VMI for a virtual-machine spawned on VMWare VCenter . All virtual-machines
// are connected on a physical-port and they are classified by the smac
// DeviceType = VM_PHYSICAL_MAC, VmiType = INTANCE and
// agent hypervisor mode = VCenter
// - VMI for service-chain virtual-machines
// - VMI for service-chain virtual-machine spawned on KVM compute node.
// It will have a TAP interface associated with it. Agent also expects a
// INSTANCE_MSG from interface associated with it.
// DeviceType = VM_ON_TAP, VmiType = SERVICE_CHAIN
// - VMI for service-instances spawned by agent itself.
// It will have a TAP interface associated with it. Agent also expects a
// INSTANCE_MSG from interface associated with it.
