Determine whether your compute node supports hardware acceleration for virtual machines:
$ egrep -c '(vmx|svm)' /proc/cpuinfo
If this command returns a value of one or greater, your compute node supports hardware acceleration which typically requires no additional configuration.
If this command returns a value of zero, your compute node does not support hardware acceleration and you must configure libvirt to use QEMU instead of KVM.
Edit the [libvirt] section in the /etc/nova/nova.conf file as follows:
[libvirt]
...
virt_type = qemu

openstack-config --set /etc/nova/nova.conf libvirt virt_type qemu

sed -i "s/SELINUX=.*/SELINUX=permissive/g" /etc/selinux/config ; setenforce 0


Configure Sysctl.conf ON ALL THE NODE
=============================================
echo 1 > /proc/sys/net/ipv4/ip_forward
grep -q net.ipv4.ip_forward /etc/sysctl.conf  ||echo "net.ipv4.ip_forward = 1 " >> /etc/sysctl.conf
