11:04 a.m.
To monitoring the network interfaces, I have a script that check if ifAdminStatus and
ifOperStatus values matches in snmp.
But with oVirt it fails on a server with 4 physical interfaces, but only two connected,
and return an error:
snmptable XXX IF-MIB::ifTable | less
SNMP table: IF-MIB::ifTable
ifIndex ifDescr ifAdminStatus ifOperStatus
1 lo up up
2 eth0 up up
3 eth1 up up
4 eth2 up down
5 eth3 up down
24 ;vdsmdummy; down down
25 vnet0 up up
And indeed on the server:
ip link show eth2
4: eth2: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc mq state DOWN mode
DEFAULT group default qlen 1000
link/ether 40:a8:f0:30:81:1a brd ff:ff:ff:ff:ff:ff
It's up, but I don't configured it on oVirt, removed ifcg-eth2. Is there a way to
disable it ?

looks like eth2 is DOWN, as expected.

eth2 seems to be in state DOWN, which seems to be reflected in
ifOperStatus.
Is the issue that ifAdminStatus is up for eth2 and eth3, but you want
it to be down?

Yes.

It's in state DOWN, but marked UP anyway.
A really DOWN interface is shown as (on another server, not an ovirt host):
4: eth2: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN mode DEFAULT group
default qlen 1000
link/ether a0:d3:c1:fa:8c:8a brd ff:ff:ff:ff:ff:ff

Yes it match. The state is reflected in the ifOperStatus. The ifAdminStatus match the UP
in the <...>
Is the issue that ifAdminStatus is up for eth2 and eth3, but you want

That's it. I never ask it to be in such state.

If eth2 and eth3 are not defined under oVirt control, I see no reason for
the system to touch it.
Perhaps, you machine has these interfaces under NetworkManager control (you
can do "nmcli device" to check it),
in that case, NM will keep the admin state up and monitor it.
If you want it down, mark the interfaces as unmanaged (by NM) and perform
an ifdown on them.
Let us know if it helped.

nmcli indeed shows:
DEVICE TYPE STATE CONNECTION
eth2 ethernet disconnected --
eth3 ethernet disconnected --
vnet0 tun disconnected --
bond0 bond unmanaged --
eth0 ethernet unmanaged --
eth1 ethernet unmanaged --
I wonder why it wants to manage vnet0 too.
That's exactly for think kind of things that I usually uninstall any NetworkManager
components on my servers. But oVirt wants it, it should them managed them:
yum erase NetworkManager
...

I added:

index 1979ea6..420aba5 100644
--- a/NetworkManager/NetworkManager.conf
+++ b/NetworkManager/NetworkManager.conf
@@ -48,3 +48,5 @@
#

And indeed it solves my problem with no unwanted side effects.
