Below Error appears:

Error: Evaluation Error: Error while evaluating a Function Call, no address for at /var/tmp/packstack/1028b99b06f84cd1825007235a5aba9a/modules/packstack/manifests/neutron/ovs_agent.pp:50:27 on node localhost

The error seems to indicate a missing tunnel interface for VXLAN.

Provide more info. Did you follow What is the network config of the host, what is the answer file?

I'm brand new to installing openstack so I may not have it but I'm pretty sure you need to properly set an FQDN for the packstack installation.

hostnamectl set-hostname

Hopefully that will help,

how do i know if shoulduyse physnet1 or extnet or eth0 ??

Comma-separated list of bridge mappings for the OpenStack

Networking Open vSwitch plugin. Each tuple in the list must be in

the format <physical_network>:<ovs_bridge>. Example: physnet1:br-



Comma-separated list of colon-separated Open vSwitch

<bridge>:<interface> pairs. The interface will be added to the

associated bridge. If you desire the bridge to be persistent a value

must be added to this directive, also

CONFIG_NEUTRON_OVS_BRIDGE_MAPPINGS must be set in order to create

the proper port. This can be achieved from the command line by

issuing the following command: packstack --allinone --os-neutron-

ovs-bridge-mappings=ext-net:br-ex --os-neutron-ovs-bridge-interfaces



Comma-separated list of Open vSwitch bridges that must be created

and connected to interfaces in compute nodes when flat or vlan type

drivers are enabled. These bridges must exist in


CONFIG_NEUTRON_OVS_BRIDGE_IFACES. Example: --os-neutron-ovs-bridges-

compute=br-vlan --os-neutron-ovs-bridge-mappings="extnet:br-

ex,physnet1:br-vlan" --os-neutron-ovs-bridge-interfaces="br-ex:eth1



Interface for the Open vSwitch tunnel. Packstack overrides the IP

address used for tunnels on this hypervisor to the IP found on the

specified interface (for example, eth1).


Appreciate your quick response in this regard
