Open Stack

Hello.

I'm now trying to deploy OpenStack Juno 3 nodes environment with
LinuxBridge on CentOS7. I set tenant_network_type to VLAN.

The problem is, a VM cannot be created and the linuxbridge agent seems not
working correctly because any port or br is shown while checking via brctl
show command.There were several error logs:

--- nova-conductor ---
No valid host was found. There are not enough hosts available.

--- nova-compute ---
NovaException: Unexpected vif_type=binding_failed

--- neutron-linuxbridge-agent ---
Device tapxxx-xxx not defined on plugin

I assume that my /etc/neutron/neutron.conf or
/etc/neutron/plugins/ml2/ml2_conf.ini configuration might be wrong, but I
cannot notice which configuration is wrongly set.

I refer to the guides on the websites;
http://docs.openstack.org/networking-guide/deploy_scenario1b.html
https://github.com/madorn/vagrant-juno-linuxbridge-vxlan-vlan

Here are my ml2_conf.ini files on each nodes as below:

1. Controller
-------------------------------------------------------------------------------------------
[ml2]
type_drivers = vlan,flat
tenant_network_types = vlan
mechanism_drivers = linuxbridge

[ml2_type_flat]
flat_networks = flat

[ml2_type_vlan]
network_vlan_ranges = vlan:1:100

[securitygroup]
enable_security_group = True
firewall_driver =
neutron.agent.linux.iptables_firewall.IptablesFirewallDriver
enable_ipset = True
-------------------------------------------------------------------------------------------

2. Compute
-------------------------------------------------------------------------------------------
[ml2]
type_drivers = vlan,flat
tenant_network_types = vlan
mechanism_drivers = linuxbridge

[ml2_type_flat]
flat_networks = flat

[ml2_type_vlan]
network_vlan_ranges = vlan:1:100

[securitygroup]
enable_security_group = True
enable_ipset = True
firewall_driver =
neutron.agent.linux.iptables_firewall.IptablesFirewallDriver

[linux_bridge]
physical_interface_mappings = vlan:eth2

[vlans]
tenant_network_type = vlan
network_vlan_ranges = vlan:1:100
-------------------------------------------------------------------------------------------

3. Network (I doesn't set flat network for external yet, so that the
physical_interface_mappings only contains one list)
-------------------------------------------------------------------------------------------
[ml2]
type_drivers = vlan,flat
tenant_network_types = vlan
mechanism_drivers = linuxbridge

[ml2_type_flat]
flat_networks = flat

[ml2_type_vlan]
network_vlan_ranges = vlan:1:100

[securitygroup]
enable_security_group = True
enable_ipset = True
firewall_driver =
neutron.agent.linux.iptables_firewall.IptablesFirewallDriver

[linux_bridge]
physical_interface_mappings = vlan:eth2

[vlans]
tenant_network_type = vlan
network_vlan_ranges = vlan:1:100
-------------------------------------------------------------------------------------------

Any comments and help would really be appreciated! Thanks in advance.

Regards
