oVirt是一个免费开源的企业级虚拟化解决方案，基于KVM（并整合了libvirt、Gluster、PatternFly和Ansible等开源软件）提供强大的开源虚拟化功能。
本文重点介绍oVirt与Tungsten Fabric的集成过程。
使用版本
ovirt 4.2.6.4-1.el7
tungsten-fabric r5.0.1
centos7.5
（编者注：本文写于2018年11月，请更新到最新版本）
建立oVirt
oVirt安装文件
https://ovirt.org/documentation/quickstart/quickstart-guide/
所有的虚拟机都来自centos7 libvirt
libvirt网络如下：
default, 192.168.122.0/24, nat
192_168_130_0, 192.168.130.0/24, isolated
节点如下：
ovirt-manager: centos161, 192.168.122.161 default
ovirt-node: centos162, 192.168.122.162, 192.168.130.162, default, 192_168_130_0
ovirt-node: centos163, 192.168.122.163, 192.168.130.163, default, 192_168_130_0
contrail-controller: centos164, 192.168.122.164, 192.168.130.164: default, 192_168_130_0
- 4vcpu, 8GB mem (24GB for contrail-controller), 48GB disk

节点设置
1、添加两台主机和一个NFS数据域。
注意：需要指定cpu类型“cpu-model”：
2、从ovirt glance导入cirros镜像。
3、在两台主机上创建cirros虚拟机，并检查虚拟机是否运行良好。
安装Tungsten Fabric
使用Tungsten Fabric r5.0.1版本
https://hub.docker.com/u/tungstenfabric/
以及ansible-deployer来安装OpenStack neutron / keystone
https://github.com/Juniper/contrail-ansible-deployer/wiki/Contrail-with-Openstack-Kolla
- instance.yaml

kolla_config:
kolla_globals:
enable_haproxy: no
enable_swift: no
kolla_passwords:

global_configuration:
CONTAINER_REGISTRY: tungstenfabric
对于ovirt-nodes，必须指定“vrouter”和“nova_compute”角色。
还需要明确指定PHYSICAL_INTERFACE，VROUTER_GATEWAY，以使vrouter能够使用eth1（与ovirtmgmt不同的NIC）。
终止nova_compute, nova_libvirt
由于vdsm使用了libvirt端口，因此需要终止nova_libvirt。
# docker stop nova_compute nova_libvirt
# docker rm nova_compute nova_libvirt
# reboot
创建OpenStack虚拟网络
键入下面的命令，以在Tungsten Fabric上创建虚拟网络。
# source /etc/kolla/kolla-toolbox/admin-openrc.sh
# openstack network create vn1
# openstack subnet create --subnet-range 10.0.1.0/24 --network vn1 subnet1
设置oVirt neutron提供程序
使用下面的参数，创建Tungsten Fabric提供程序。
Name: tungsten-fabric
Network Plugin: LINUX_BRIDGE
Provider URL: http://192.168.122.164:9696
Read-Only: Checked
Requires Authentication: Checked
Username: admin
Password: contrail123
Tenant /name: admin
Authentication URL: http://192.168.122.164:35357/v2.0
从Tungsten Fabric导入虚拟网络
添加vdsm hook
在下面的目录找到文件：
/usr/libexec/vdsm/hooks/after_device_create/60_tungsten-fabric
- 注意：部署时需要给出tf_controller_ip
#!/usr/bin/python
import os
import requests
tf_controller_ip='192.168.122.164'
vnic_id=os.environ['vnic_id']
re = requests.get('http://{}:8082/virtual-machine-interface/{}'.format (tf_controller_ip, vnic_id))
js = re.json()['virtual-machine-interface']
mac_addr = js['virtual_machine_interface_mac_addresses']['mac_address'][0]
vm_id = js['virtual_machine_refs'][0]['to'][0]
vn_id = js['virtual_network_refs'][0]['uuid']
cmd = "/var/lib/docker/volumes/opt_plugin/_data/bin/vrouter-port-control --oper=add --uuid={} --instance_uuid={} --vn_uuid={} --vm_name='' --ip_address='0.0.0.0' --ipv6_address=None --tap_name=tap{} --mac='{}' --rx_vlan_id=-1 --tx_vlan_id=-1".format(vnic_id, vm_id, vn_id, vnic_id[:11], mac_addr)
os.popen(cmd).read()
# chmod 755 /usr/libexec/vdsm/hooks/after_device_create/60_tungsten-fabric
# chmod 755 /var/lib/docker/volumes/
创建虚拟机并将vNIC附加到TF虚拟网络上
登录到cirros并检查是否能正常ping通：
# ping 10.0.1.1 # gw-ip
# ping 10.0.1.2 # service-ip
# ping (cirros ip on different ovirt node)
