I have built a new host and my setup is a single hyperconverged node.. I followed the directions to create a new logical network. I see that the engine has marked the network as being down. (Hosts>Network Interfaces Tab>Setup Host Networks) Here is my network config on the host- [root@vmh ~]# ip a 1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000 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: enp96s0f0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq master ovirtmgmt state UP group default qlen 1000 link/ether 0c:c4:7a:f9:b9:88 brd ff:ff:ff:ff:ff:ff 3: enp96s0f1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP group default qlen 1000 link/ether 0c:c4:7a:f9:b9:89 brd ff:ff:ff:ff:ff:ff inet 172.30.51.2/30 brd 172.30.51.3 scope global noprefixroute dynamic enp96s0f1 valid_lft 82411sec preferred_lft 82411sec inet6 fe80::d899:439c:5ee8:e292/64 scope link noprefixroute valid_lft forever preferred_lft forever 19: ;vdsmdummy;: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN group default qlen 1000 link/ether 96:e4:00:aa:71:f7 brd ff:ff:ff:ff:ff:ff 23: ovs-system: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN group default qlen 1000 link/ether 36:0f:60:69:e1:2b brd ff:ff:ff:ff:ff:ff 24: br-int: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN group default qlen 1000 link/ether f6:3b:14:e1:15:48 brd ff:ff:ff:ff:ff:ff 25: ovirtmgmt: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP group default qlen 1000 link/ether 0c:c4:7a:f9:b9:88 brd ff:ff:ff:ff:ff:ff inet 172.30.50.3/24 brd 172.30.50.255 scope global dynamic ovirtmgmt valid_lft 84156sec preferred_lft 84156sec inet6 fe80::ec4:7aff:fef9:b988/64 scope link valid_lft forever preferred_lft forever 26: vnet0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq master ovirtmgmt state UNKNOWN group default qlen 1000 link/ether fe:16:3e:50:53:cd brd ff:ff:ff:ff:ff:ff inet6 fe80::fc16:3eff:fe50:53cd/64 scope link valid_lft forever preferred_lft forever VLAN 101 is attached to enp96s0f0 which is my ovirtmgmt interface. -IP range 172.30.50.x VLAN 102 is attached to enp96s0f1 which is my storage NIC for gluster. -IP range 172.30.51.x VLAN 103 is attached to enp96s0f1 is intended for most of my VMs that are not infrastructure related. -IP range 192.168.2.x I am pretty confident my router/switch is setup correctly.. As a test, I can go to localhost>networking>add VLAN and assign enp96s0f1 to VLAN 103 and it does get an IP address in the 192.168.2.x range. The host can also ping the 192.168.2.1 gateway. Why doesn't the engine think the VLAN is up? Which logs do I need to review?
