Re: [ovirt-users] oVirt and Openstack Neutron: network not working

What do you mean? there is no firewall between openstack controllers and ovirt engine/hosts. My doubt is about configuration, i've configured in this way: Name: openstack-networks Type: OpenStack Networking Description: Provider URL: http://openstack.example.com:9696 Flagged read-only and requires authentication Set the authentication and tested, reports everything ok. Nothing else has been configured. I didn't found any documentation that clarified if is enough. After powering on i see on openstack this: [stack@opstrio1101 ~]$ openstack port list | grep 00:1a:4a:16:01:51 <-- this is mac address of oVirt VM | 86c46fed-dddf-4776-a765-27d4e52e861c | nic1 | 00:1a:4a:16:01:51 | ip_address='172.25.7.4', subnet_id='280a98ad-0fd5-4961-a307-d1bfea8355cd' | This are the output of the commands you asked from a node where a vm that is attached to a neutron network is running: [root@ovirt002 ~]# ip addr 1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN qlen 1 link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 inet 127.0.0.1/8 scope host lo valid_lft forever preferred_lft forever inet6 ::1/128 scope host valid_lft forever preferred_lft forever 2: enp2s0f0: <BROADCAST,MULTICAST,SLAVE,UP,LOWER_UP> mtu 1500 qdisc mq master bond0 state UP qlen 1000 link/ether 00:21:5a:9b:b7:93 brd ff:ff:ff:ff:ff:ff 3: enp2s0f1: <BROADCAST,MULTICAST,SLAVE,UP,LOWER_UP> mtu 1500 qdisc mq master bond0 state UP qlen 1000 link/ether 00:21:5a:9b:b7:93 brd ff:ff:ff:ff:ff:ff 4: enp2s0f2: <BROADCAST,MULTICAST,SLAVE,UP,LOWER_UP> mtu 1500 qdisc mq master bond1 state UP qlen 1000 link/ether 00:21:5a:9b:b7:97 brd ff:ff:ff:ff:ff:ff 5: enp2s0f3: <BROADCAST,MULTICAST,SLAVE,UP,LOWER_UP> mtu 1500 qdisc mq master bond1 state UP qlen 1000 link/ether 00:21:5a:9b:b7:97 brd ff:ff:ff:ff:ff:ff 6: enp2s0f4: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc mq state DOWN qlen 1000 link/ether 00:21:5a:9b:b7:9b brd ff:ff:ff:ff:ff:ff 7: enp2s0f5: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc mq state DOWN qlen 1000 link/ether 00:21:5a:9b:b7:9d brd ff:ff:ff:ff:ff:ff 8: enp2s0f6: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc mq state DOWN qlen 1000 link/ether b4:b5:2f:55:bc:eb brd ff:ff:ff:ff:ff:ff 9: enp2s0f7: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc mq state DOWN qlen 1000 link/ether b4:b5:2f:55:bc:ef brd ff:ff:ff:ff:ff:ff 10: bond0: <BROADCAST,MULTICAST,MASTER,UP,LOWER_UP> mtu 1500 qdisc noqueue master ovirtmgmt state UP qlen 1000 link/ether 00:21:5a:9b:b7:93 brd ff:ff:ff:ff:ff:ff 11: ovirtmgmt: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP qlen 1000 link/ether 00:21:5a:9b:b7:93 brd ff:ff:ff:ff:ff:ff inet 10.5.40.192/22 brd 10.5.43.255 scope global ovirtmgmt valid_lft forever preferred_lft forever inet6 fe80::221:5aff:fe9b:b793/64 scope link valid_lft forever preferred_lft forever 12: bond1: <BROADCAST,MULTICAST,MASTER,UP,LOWER_UP> mtu 1500 qdisc noqueue master NFS state UP qlen 1000 link/ether 00:21:5a:9b:b7:97 brd ff:ff:ff:ff:ff:ff 13: NFS: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP qlen 1000 link/ether 00:21:5a:9b:b7:97 brd ff:ff:ff:ff:ff:ff inet 10.5.160.46/22 brd 10.5.163.255 scope global NFS valid_lft forever preferred_lft forever inet6 fe80::221:5aff:fe9b:b797/64 scope link valid_lft forever preferred_lft forever 14: ;vdsmdummy;: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN qlen 1000 link/ether be:ae:6d:b7:0f:f5 brd ff:ff:ff:ff:ff:ff 16: qvo86c46fed-dd@qvb86c46fed-dd: <BROADCAST,MULTICAST,PROMISC,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP qlen 1000 link/ether 5e:d1:06:97:f0:19 brd ff:ff:ff:ff:ff:ff inet6 fe80::5cd1:6ff:fe97:f019/64 scope link valid_lft forever preferred_lft forever 17: qvb86c46fed-dd@qvo86c46fed-dd: <BROADCAST,MULTICAST,PROMISC,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP qlen 1000 link/ether e6:73:ee:8e:03:09 brd ff:ff:ff:ff:ff:ff inet6 fe80::e473:eeff:fe8e:309/64 scope link valid_lft forever preferred_lft forever 18: qbr86c46fed-dd: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN qlen 1000 link/ether fe:1a:4a:16:01:51 brd ff:ff:ff:ff:ff:ff 21: tap86c46fed-dd: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast master qbr86c46fed-dd state UNKNOWN qlen 1000 link/ether fe:1a:4a:16:01:51 brd ff:ff:ff:ff:ff:ff [root@ovirt002 ~]# brctl show bridge name bridge id STP enabled interfaces ;vdsmdummy; 8000.000000000000 no NFS 8000.00215a9bb797 no bond1 ovirtmgmt 8000.00215a9bb793 no bond0 qbr86c46fed-dd 8000.fe1a4a160151 no tap86c46fed-dd [root@ovirt002 ~]# ovs-vsctl show ovs-vsctl: unix:/var/run/openvswitch/db.sock: database connection failed (No such file or directory) If you need other clarifications i'll dig without problem in this env.
