I have tried to install openstack on Centos 7.
Below are the configurations:
# egrep -c '(vmx|svm)' /proc/cpuinfo
gives an output of 24
I have followed the online documentation: OPENSTACK INSTALLATION GUIDE FOR RED HAT ENTERPRISE LINUX 7, CENTOS 7, AND FEDORA 20 - JUNO (Install and configure network node) line by line and verified all configurations 3 times.
Now whenever I try to launch instances using the Horizon dashboard, I get this error No Valid Host was found!!
Nova-compute Log gives me this 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 are my neutron and compute node network interfaces http://pastebin.com/vJyCy5zc
Nova.conf file on the Compute node http://pastebin.com/RvYkUEfW
I have searched google, openstack forum and elsewhere and tried all their suggestions, but the issue remains unsolved. Here is a link to my openstack-forum question: Unable to launch instances (Unexpected vif_type=binding failed)
Also note that I do not have any connectivity issues to the AMQP server on the controller, as I get successfully connected message in my logs.
All my openstack services are up and running properly
Has anyone faced a similar issue? I have been struggling with this issue, since last 2 weeks.
Any help will be deeply revered.

Modify /etc/nova/nova.conf file and increase the allocation ratio .
cpu_allocation_ratio
and memory_allocation_ratio
in compute node .
Restart the nova and nova-scheduler service in compute node
systemctl restart openstack-nova-*
systemctl restart openstack-nova-scheduler.service
