You're using the wrong cloud.. You should be using OpenNebulaand 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.

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.
