Hello Steven,
That's what happens when you work with both cloud solutions and do not
pay enough attention to which list you are posting...
Sorry for the inconvenience, and do as it never happened :)

You're using the wrong cloud.. You should be using OpenNebula
and not OpenStack and then you would not be having these OpenStack
problems. Probably better to get help on OpenStack on the OpenSTack
list.

Hello all,
Here it is my situation:
I am trying to install Essex on a small cluster (3 nodes) running
Debian.
There is a front-end node that has a public IP and then there are 2
compute
nodes in a LAN. I cannot run nova-network on the front-end node
because it
is overwritting the iptables there and some other services start to
misbehave, so I am trying a multi-host solution with nova-network
running in
each compute node.
The nova.conf I'm using in both compute nodes is the following:
[DEFAULT]
logdir=/var/log/nova
state_path=/var/lib/nova
lock_path=/var/lock/nova
root_helper=sudo nova-rootwrap
auth_strategy=keystone
iscsi_helper=tgtadm
sql_connection=mysql://nova-common:[email protected]/nova
connection_type=libvirt
libvirt_type=kvm
my_ip=172.16.8.22
rabbit_host=172.16.8.1
glance_host=172.16.8.1
image_service=nova.image.glance.GlanceImageService
network_manager=nova.network.manager.FlatDHCPManager
fixed_range=192.168.100.0/24
flat_interface=eth1
public_interface=eth0
flat_network_bridge=br100
flat_network_dhcp_start=192.168.100.2
network_size=256
dhcpbridge_flagfile=/etc/nova/nova.conf
dhcpbridge=/usr/bin/nova-dhcpbridge
multi_host=True
send_arp_for_ha=true
I have created a network with:
nova-manage network create private --fixed_range_v4=192.168.100.0/24
--multi_host=T --bridge_interface=br100
And I have set up eth1 with no IP and running in promisc mode. When I
launch
an instance, ifconfig outputs the following:
br100 Link encap:Ethernet HWaddr 68:b5:99:c2:7b:a7

And brctl show:
bridge name bridge id STP enabled interfaces
br100 8000.68b599c27ba7 no eth1
?? ? vnet0
Which looks fine to me. However, the VM log shows that it is unable
to get
an IP through DHCP (despite dnsmasq is running):
Starting network...
udhcpc (v1.18.5) started
Sending discover...
Sending discover...
Sending discover...
No lease, failing
WARN: /etc/rc3.d/S40-network failed
What am I doing wrong? Any help would be very much appreciated.
Thanks in advance,
