Hi Bill,

First, i would strongly suggest that you check whether the interfaces are e=
xplcicitly NOT managed by NetworkManager, thats the way we do it.

We have something like this

=97

DEVICE=3Dovirtmgmt
TYPE=3DBridge
DELAY=3D0
STP=3Doff
ONBOOT=3Dyes
IPADDR=3D
NETMASK=3D
GATEWAY=3D
BOOTPROTO=3Dnone
DEFROUTE=3Dyes
NM_CONTROLLED=3Dno
HOTPLUG=3Dno

----

And

=97
DEVICE=3Dbond0
BONDING_OPTS=3D'miimon=3D100 updelay=3D0 downdelay=3D0 mode=3D802.3ad xmit_=
hash_policy=3Dlayer3+4'
BRIDGE=3Dovirtmgmt
ONBOOT=3Dyes
NM_CONTROLLED=3Dno
HOTPLUG=3Dno
---

Physical interfaces

=97

DEVICE=3Dp3p3
HWADDR=3D
MASTER=3Dbond0
SLAVE=3Dyes
ONBOOT=3Dyes
MTU=3D1500
NM_CONTROLLED=3Dno

=97

And we actually create all the interfaces BEFORE ovirt installation even th=
ough 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=85 =93had=94=
 being the operative word here.

Today I connected the second network interface and then went to the host an=
d tried to bond this interface to the ovirt mgmt. network=85 this is where =
the =93had=94 part comes in ;-)

Now I have no working interfaces at all, can=92t ping in or out and all int=
erfaces 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 we=
ll, very impressed with it.

The differences are=85

RHEV cluster I was using trunked ports and VLANS
RHEV I was using 6.4 or 6.5 RHEL

I think that=92s it.

I haven=92t really dug into the /etc/sysconfig/network-scripts to see what =
normally goes into the config files to create a bonded interface =96 only t=
o see how to configure my first interface with a vlan and then I let ovirte=
ngine 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=92s just PoC anyway, so learning.

Thanks
