hi, just to understand. i access compute node from director with ssh heat-admin@192.168.100.32

then in this compute ip a eno1: <broadcast,multicast,up,lower_up> mtu 1500 qdisc mq state UP group default qlen 1000 inet 192.168.100.32/24 brd 192.168.100.255 scope global eno1 6: eno2: <broadcast,multicast,up,lower_up> mtu 1500 qdisc mq state UP group default qlen 1000 519: qbr9ddf95c1-cd: <broadcast,multicast,up,lower_up> mtu 2140 qdisc noqueue state UP group default qlen 1000 7: enp94s0f1: <broadcast,multicast,slave,up,lower_up> mtu 2140 qdisc mq master bond-tenant state UP group default qlen 1000 520: qvo9ddf95c1-cd@qvb9ddf95c1-cd: <broadcast,multicast,promisc,up,lower_up> mtu 2140 qdisc noqueue master ovs-system state UP group default qlen 1000 8: eno3: <broadcast,multicast,slave,up,lower_up> mtu 1500 qdisc mq master bond-ext state UP group default qlen 1000 521: qvb9ddf95c1-cd@qvo9ddf95c1-cd: <broadcast,multicast,promisc,up,lower_up> mtu 2140 qdisc noqueue master qbr9ddf95c1-cd state UP group default qlen 1000 522: qbrf055407a-a1: <broadcast,multicast,up,lower_up> mtu 2140 qdisc noqueue state UP group default qlen 1000 10: ovs-system: <broadcast,multicast> mtu 1500 qdisc noop state DOWN group default qlen 1000 523: qvof055407a-a1@qvbf055407a-a1: <broadcast,multicast,promisc,up,lower_up> mtu 2140 qdisc noqueue master ovs-system state UP group default qlen 1000 11: br-int: <broadcast,multicast> mtu 2140 qdisc noop state DOWN group default qlen 1000 524: qvbf055407a-a1@qvof055407a-a1: <broadcast,multicast,promisc,up,lower_up> mtu 2140 qdisc noqueue master qbrf055407a-a1 state UP group default qlen 1000 12: vxlan_sys_4789: <broadcast,multicast,up,lower_up> mtu 65000 qdisc noqueue master ovs-system state UNKNOWN group default qlen 1000 525: qbr59036b80-61: <broadcast,multicast,up,lower_up> mtu 2140 qdisc noqueue state UP group default qlen 1000 18: bond-tenant: <broadcast,multicast,master,up,lower_up> mtu 2140 qdisc noqueue master ovs-system state UP group default qlen 1000

where eno2 and en03 -in bond-tenant. is that mean that the virtual machines on compute are connected to this bond or to br-int? tnx

To answer the question in the last paragraph: Instances are directly connected to physical interfaces or bonds when using SRIOV. I don’t know if and how TripleO supports it.

Without SRIOV, instances must be connected to a bridge or switch, which is usually named br-int (“integration bridge”).
