Xen Virtualization on Linux and Solaris: RDO Kilo Set up for three VM Nodes (Controller+Network+Compute) ML2&OVS&VXLAN on CentOS 7.1

Following bellow is brief instruction for traditional three node deployment test Controller&&Network&&Compute for oncoming RDO Kilo, which was performed on Fedora 21 host with KVM/Libvirt Hypervisor (16 GB RAM, Intel Core i7-4790 Haswell CPU, ASUS Z97-P ) Three VMs (4 GB RAM,2 VCPUS) have been setup. Controller VM one (management subnet) VNIC, Network Node VM three VNICS (management,vtep's external subnets), Compute Node VM two VNICS (management,vtep's subnets)

SELINUX stays in enforcing mode.

I avoid using default libvirt subnet 192.168.122.0/24 for any purposes related
with VM serves as RDO Kilo Nodes, by some reason it causes network congestion when forwarding packets to Internet and vice versa.

Three Libvirt networks created

1. First Libvirt subnet "openstackvms" serves as management network.
All 3 VM are attached to this subnet
**********************************************************************************
2. Second Libvirt subnet "public" serves for simulation external network Network Node attached to public,latter on "eth3" interface (belongs to "public") is supposed to be converted into OVS port of br-ex on Network Node. This Libvirt subnet via bridge virbr2 172.24.4.25 provides VMs running on Compute Node access to Internet due to match to external network created by packstack installation 172.24.4.224/28.

# chkconfig network on
# systemctl stop NetworkManager

OVS PORT should be eth2 (third Ethernet interface on Network Node)
Libvirt bridge VIRBR2 in real deployment is a your router to External
network. OVS BRIDGE br-ex should have IP belongs to External network
