Hi Bill,
First, i would strongly suggest that you check whether the interfaces are explcicitly NOT managed by NetworkManager, thats the way we do it.
We have something like this
—
DEVICE=ovirtmgmt
TYPE=Bridge
DELAY=0
STP=off
ONBOOT=yes
IPADDR=
NETMASK=
GATEWAY=
BOOTPROTO=none
DEFROUTE=yes
NM_CONTROLLED=no
HOTPLUG=no
----
And
—
DEVICE=bond0
BONDING_OPTS='miimon=100 updelay=0 downdelay=0 mode=802.3ad xmit_hash_policy=layer3+4'
BRIDGE=ovirtmgmt
ONBOOT=yes
NM_CONTROLLED=no
HOTPLUG=no
---
Physical interfaces
—
DEVICE=p3p3
HWADDR=
MASTER=bond0
SLAVE=yes
ONBOOT=yes
MTU=1500
NM_CONTROLLED=no
—
And we actually create all the interfaces BEFORE ovirt installation even though the files will be regenerated after installing and configuring ovirt (vdsm)
That works like a charm for us
Cheers
Soeren

Subject: [ovirt-users] bonding interfaces
Hi,
I had a Gluster Cluster running that I setup with oVirt engine… “had” being the operative word here.
Today I connected the second network interface and then went to the host and tried to bond this interface to the ovirt mgmt. network… this is where the “had” part comes in ;-)
Now I have no working interfaces at all, can’t ping in or out and all interfaces say they are down, en1, 2, ovrtmgmt and bond0 when I do an ip add (this is centos7)
I have done this quite a few times on RHEV clusters and it always worked well, very impressed with it.
The differences are…
RHEV cluster I was using trunked ports and VLANS
RHEV I was using 6.4 or 6.5 RHEL
I think that’s it.
I haven’t really dug into the /etc/sysconfig/network-scripts to see what normally goes into the config files to create a bonded interface – only to see how to configure my first interface with a vlan and then I let ovirtengine do the rest for me as it worked so wellI
I guess I may have to rip it out and start over unless anyone has any tips on fixing it. It’s just PoC anyway, so learning.
Thanks
