Sam Betts 6df49741dd [Devstack] Rework VMs connection logic ... Devstack currently plugs the simulated baremetal VMs into OVS using the libvirt bridge driver, this caused a problem because libvirt unplugs the VM from the network when it is turned off. To fix this an extra bridge was added between the VM and OVS to allow the OVS port to persist even when the VM was turned off. This patch replaces how the devstack simulated baremetal VMs are plugged into OVS with a manually created tap interface, this removes the need for an extra bridge, because manually created tap interfaces aren't unplugged when the VM is turned off. Allow to connect several interfaces to a node by setting IRONIC_VM_INTERFACE_COUNT devstack variable.
