Would you please share the vdsm.log and the supervdsm.log from this host? On Wed, 22 Aug 2018 11:36:09 -0400 Douglas Duckworth <dod2014@med.cornell.edu> wrote:

Hi

I keep losing ib0 connection on hypervisor after adding host to engine. This makes the host not really work since NFS will be mounted over ib0.

I don't really understand why this occurs.

OS:

[root@ovirt-hv2 ~]# cat /etc/redhat-release CentOS Linux release 7.5.1804 (Core)

Here's the network script:

[root@ovirt-hv2 ~]# cat /etc/sysconfig/network-scripts/ifcfg-ib0 DEVICE=ib0 BOOTPROTO=static IPADDR=172.16.0.207 NETMASK=255.255.255.0 ONBOOT=yes ZONE=public

When I try "ifup"

[root@ovirt-hv2 ~]# ifup ib0 Error: Connection activation failed: No suitable device found for this connection.

The error in syslog:

Aug 22 11:31:50 ovirt-hv2 kernel: IPv4: martian source 172.16.0.87 from 172.16.0.49, on dev ib0 Aug 22 11:31:53 ovirt-hv2 NetworkManager[1070]: <info> [1534951913.7486] audit: op="connection-activate" uuid="2ab4abde-b8a5-6cbc-19b1-2bfb193e4e89" name="System ib0" result="fail" reason="No suitable device found for this connection.

As you can see media state up:

The card is FDR:

I can add an IP to ib0 using "ip addr" though I need Network Manager to work with ib0.
