Following bellow a simple two node Controller&&Network and Compute test for oncoming RDO Kilo, which was performed on Fedora 21 host with KVM/Libvirt Hypervisor (16 GB RAM, i5-4690 Intel CPU,ASUS Z97-P Board)
Two VMs (6 GB RAM, 2 VCPUS) have been setup , each one having 2 VNICs (eth0,eth1) for Controller && Compute Nodes emulation. SELINUX stays in enforcing mode. Both eth1's assigned IPs and set support VXLAN tunnel
(192.168.122.127, 192.168.122.137 ). Packstack is bind to public IP of interface eth0
192.169.142.127, Compute Node is 192.169.1.137 ( view answer-file ).
****************************************
Create non-default libvirt subnet
****************************************
1. Create a new libvirt network (other than your default 192.168.122.x) via XML file:
$ cat devstackvms.xml
<network>
<name>devstackvms</name>
<uuid>d0e9964a-f91a-40c0-b769-a609aee41bf2</uuid>
<forward mode='nat'>
<nat>
<port start='1024' end='65535'/>
</nat>
</forward>
<bridge name='virbr1' stp='on' delay='0' />
<mac address='52:54:00:60:f8:6e'/>
<ip address='192.169.142.1' netmask='255.255.255.0'>
<dhcp>
<range start='192.169.142.2' end='192.169.142.254' />
</dhcp>
</ip>
</network>
$ virsh net-define devstackvms.xml
Then start the network and enable "autostart"
$ virsh net-start devstackvms
$ virsh net-autostart devstackvms
Setup configuration
- Controller node: Nova, Keystone, Cinder, Glance, Neutron(ML2&OVS&VXLAN)
- Compute node: Nova (nova-compute), Neutron (openvswitch-agent)
Controller && Network Node - ip-192-169-142-127.ip.secureserver.net
Compute Node - ip-192-169-142-137.ip.secureserver.net

Procedure to enable nested virtualization (on Intel-based machines) [
1 ]
********************************************************************************
1. List modules and ensure KVM Kernel modules are enabled on L0:
$ lsmod | grep -i kvm
kvm_intel 133627 0
kvm 435079 1 kvm_intel
2. Show information for `kvm_intel` module:
$ modinfo kvm_intel | grep -i nested
parm: nested:boolkvm 435079 1 kvm_intel
3. Ensure nested virt is persistent across reboots by adding it as a
config directive:
$ cat /etc/modprobe.d/dist.conf
options kvm-intel nested=y
4. Reboot the host.
5. Check if the Nested KVM Kernel module option is enabled:
$ cat /sys/module/kvm_intel/parameters/nested
Y
6. Before you boot your L1 guest (i.e. the guest hypervisor that runs
the nested guest), expose virtualization extensions to it. The
following exposes all the CPU features of host to your guest
unconditionally:
[root@fedora21wks01 ~]# cat /sys/module/kvm_intel/parameters/nested
Y
[root@fedora21wks01 ~]# virsh list --all
