Flat network IP assignment to bridge on additional compute node

Asked by S.A. on 2012-10-01

Hello,

I have a working controller (with a compute node) and an additional compute node. Then there was a VM information loss and the trouble started for me. By the time I had a chance to clean-up the orphaned VM instance, I seems to have messed something else up! As it stands now, controller (with compute node) works, and the additional compute node works, however the instances created on the additional node can't be reached from any where. The reason for this is because the flat network IP was not assigned to the bridge interface (br100) on the additional compute node. I have identical nova.conf files on both servers, excepting for the following parameters:
    novncproxy_base_url
    vncserver_listen
    vncserver_proxyclient_address

I can see my controller bridge (br100) with a flat network IP, but not the bridge on the additional node.

Both hosts are CentOS 6.3 with KVM for VMs.

Network configuration from /etc/nova/nova.conf
network_manager = nova.network.manager.FlatDHCPManager
dhcpbridge = /usr/bin/nova-dhcpbridge
dhcpbridge_flagfile = /etc/nova/nova.conf
flat_network_dhcp_start = 10.0.0.2
force_dhcp_release = True
flat_network_bridge=br100
flat_interface=eth0
public_interface=eth0
multi_host=True

Any pointers?
