br100 setup and nova fixed ip range
This is my situation:
- An ESXi 5.0 Server (I'm doing a project for my BD);
- A pool with 2 VM (1 controller node and 1 compute node)
- Ubuntu 13.04 amd64 Server installed on both VM
- The controller IP is 172.25.27.11
- i've successfully setup keystone, glance and partially nova
My problem with nova is the creation of the br100 and the fixed range subnet.
Inside the /etc/network/interfaces
file i have:
auto lo
iface lo inet loopback
auto eth0
iface eth0 inet dhcp
auto br100
iface br100 inet dhcp
bridge_ports eth0
bridge_stp off
bridge_fd 0
bridge_maxwait 0
inside the file /etc/nova/nova.conf
i have:
# NETWORK
network_manger_nova=nova.network.manger.FlatDHCPManager
my_ip=172.25.27.11
fixed_range=172.25.27.0/24
public_interface=eth0
vlan_interface=eth0
flat_interface=eth0
flat_network_bridge=br100
I have also enabled ip forwarding inside /etc/sysctl.conf
and i have set eth0 promisc with ip link set eth0 promisc on
.
The cmd brctl show
show:
bridge name bridge id STP enabled interfaces
br100 8000.xxxx no eth0
What i am doing wrong?
Take a look here from my answer: https://ask.openstack.org/question/508/trying-to-integrate-vms-to-existing-lan/
on the controller node have i to write
br100 ecc ecc
insideetc/network/interfaces
??No, just on compute node.
thanks, you've solved my problem :D :D
ps last thing: eth0 have to be set "promisc on" or off?
