Openvim support 2 dhcp server options, bridge or ovs

----
== DHCP server (Bridge)==

Modify '''openvimd.cfg''' and add net controller connection details:

network_type : bridge

For the management network a DHCP server is needed. Install the package dhcp3-server. This package will install the actual DHCP server based on isc-dhcp-server package.

Ubuntu 14.04: sudo apt-get install dhcp3-server
Ubuntu 16.04: sudo apt install isc-dhcp-server

Configure it editing file '''/etc/default/isc-dhcp-server''' to enable DHCP server in the appropriate interface, the one attached to Telco/VNF management network (e.g. eth1).

$ sudo vi /etc/default/isc-dhcp-server
INTERFACES="eth1"

Edit file '''/etc/dhcp/dhcpd.conf''' to specify the subnet, netmask and range of IP addresses to be offered by the server.

$ sudo vi /etc/dhcp/dhcpd.conf
ddns-update-style none;
default-lease-time 86400;
max-lease-time 86400;
log-facility local7;
option subnet-mask 255.255.0.0;
option broadcast-address 10.210.255.255;
subnet 10.210.0.0 netmask 255.255.0.0 {
range 10.210.1.2 10.210.1.254;
}

Restart the service:

sudo service isc-dhcp-server restart

----
== Openvim OVS controller==

For DHCP management through OVS networks, some preparation is need it before.

Execute '''scripts/configure-dhcp-server-UBUNTU16.0.4.sh''' to prepare openvim net controller. Can be placed in the same Openvim VM or in a new one.

''$sudo ./openvim/scripts/configure-dhcp-server-UBUNTU16.0.4.sh <user-name>''

Modify '''openvimd.cfg''' and add net controller connection details:

network_type : ovs
ovs_controller_ip: <net controller ip> # dhcp controller IP address, must be change in
# order to reach computes.
ovs_controller_user: <net controller user> # User for the dchp controller for OVS networks
ovs_controller_file_path: '/var/lib/openvim' # Net controller Path for dhcp daemon
# configuration, by default '/var/lib/openvim

For automatic login from openvim controller to OVS controller computes fill the ovs_controller_keyfile path to the public ssh key must be specify in openvimd.cfg.

ovs_controller_keyfile: /path/to/ssh-key-file # ssh-access-key file to connect host
host_ssh_keyfile: /path/to/ssh-key-file # Default ssh_kye to use for connecting to compute nodes
