Openstack Failed to launch Instances [Error: No Valid Host was found] -


i have tried install openstack on centos 7.
below configurations:

  1. neutron node (vm 2 vcpu, 2 gb ram , 3 nics)
  2. controller node(vm 2 vcpu, 8 gb ram, 1 nic)
  3. compute node(physical machine 24 cpu, 64 gb ram, 2 nic)
    # egrep -c '(vmx|svm)' /proc/cpuinfo gives output of 24

i have followed online documentation: openstack installation guide red hat enterprise linux 7, centos 7, , fedora 20 - juno (install , configure network node) line line , verified configurations 3 times.

now whenever try launch instances using horizon dashboard, error no valid host found!!

nova-compute log gives me error

nova-compute.log

2015-08-21 22:55:00.391 41235 trace nova.compute.manager [instance: d9bfa207->6e85-4ca8-a385-52d90818a49b] _("unexpected vif_type=%s") % vif_type) 2015-08-21 22:55:00.391 41235 trace nova.compute.manager [instance: d9bfa207->6e85-4ca8-a385-52d90818a49b] novaexception: unexpected vif_type=binding_failed

these neutron , compute node network interfaces http://pastebin.com/vjycy5zc

nova.conf file on compute node http://pastebin.com/rvykuefw

i have searched google, openstack forum , elsewhere , tried suggestions, issue remains unsolved. here link openstack-forum question: unable launch instances (unexpected vif_type=binding failed)

also note not have connectivity issues amqp server on controller, connected message in logs.

all openstack services , running has faced similar issue? have been struggling issue, since last 2 weeks.
