# **DHCP Warning**: If your flat interface device uses DHCP, there will be a

# hiccup while the network is moved from the flat interface to the flat network

# bridge. This will happen when you launch your first instance. Upon launch

# you will lose all connectivity to the node, and the VM launch will probably

# fail.

#

# If you are running on a single node and don't need to access the VMs from

# devices other than that node, you can set ``FLAT_INTERFACE=``

# This will stop nova from bridging any interfaces into ``FLAT_NETWORK_BRIDGE``.
