Hello all,<br>
<br>
Here it is my situation:<br>
<br>
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.<br>
<br>
The nova.conf I'm using in both compute nodes is the following:<br>
<br>
[DEFAULT]<br>
logdir=/var/log/nova<br>
state_path=/var/lib/nova<br>
lock_path=/var/lock/nova<br>
root_helper=sudo nova-rootwrap<br>
auth_strategy=keystone<br>
iscsi_helper=tgtadm<br>
<a class="moz-txt-link-abbreviated" href="mailto:sql_connection=mysql://nova-common:password@172.16.8.1/nova">sql_connection=mysql://nova-common:password@172.16.8.1/nova</a><br>
connection_type=libvirt<br>
libvirt_type=kvm<br>
my_ip=172.16.8.22<br>
rabbit_host=172.16.8.1<br>
glance_host=172.16.8.1<br>
image_service=nova.image.glance.GlanceImageService<br>
network_manager=nova.network.manager.FlatDHCPManager<br>
fixed_range=192.168.100.0/24<br>
flat_interface=eth1<br>
public_interface=eth0<br>
flat_network_bridge=br100<br>
flat_network_dhcp_start=192.168.100.2<br>
network_size=256<br>
dhcpbridge_flagfile=/etc/nova/nova.conf<br>
dhcpbridge=/usr/bin/nova-dhcpbridge<br>
multi_host=True<br>
send_arp_for_ha=true<br>
<br>
I have created a network with:<br>
<br>
nova-manage network create private --fixed_range_v4=192.168.100.0/24
--multi_host=T --bridge_interface=br100<br>
<br>
And I have set up eth1 with no IP and running in promisc mode. When
I launch an instance, ifconfig outputs the following:<br>

<br>
Which looks fine to me. However, the VM log shows that it is unable
to get an IP through DHCP (despite dnsmasq is running):<br>

What am I doing wrong? Any help would be very much appreciated.<br>

Thanks in advance,<br>
