Hi Nicolas,
Yes I would do a double test with both bonding and teaming and see if the agent
simply doesn’t like teaming at all.
You can obviously also change the agent logs to trace and see if that sheds
more light on it.
With regards to naming convention I know this is a contested issue – we do the
same as you and change it back to the legacy ethX naming convention to simplify
our build scripts, but overall I would expect it to work with the new world
naming convention.

Dag,
okay, i got it, thanks a lot for the details and your help.
As im stuck with the current configuration with nmcli, im going to try
without on an another host see if i have more success.
Do you know if someone success to set up KVM networking with the new naming
convention on centOS7 ? (ensX, enpX..etc)
because i renamed the NICs with ethX but don't know if it was really
necessary.
Best regards,
N.B

Hi Nicolas
These two settings are mutually exclusive – you are controlling your
networking with NetworkManager (NM) through nmcli. My personal preference is to
leave NM out of the equation and do all configuration manually (or with
Ansible, Chef or whatever tool you choose) – hence I mark the different
interfaces with "NM_CONTROLLED=no" to stop NM ever trying to interfere if
someone starts the NM service up.
So – if you want to use nmcli then remove "NM_CONTROLLED=no" from your
config files.
As I said – this is a personal preference only though – you will probably
manage to get it to work with NM, I just find it too intrusive.

Hi Dag,
You are right, and i did it, it was not clear enought on my first mail.
I add the ethX interface to the team-MGMT with this command :
nmcli con add type ethernet con-name MGMT-port1 ifname eth0 master MGMT
Here the configuration :
############### MGMT-port1 ############
NAME=MGMT-port1
UUID=xxxx-xxxxx...etc
DEVICE=eth0
TEAM_MASTER=MGMT
DEVICETYPE=TeamPort
i just tried with adding "NM_CONTROLLED=no" but its worse, now, i
can't even contact cloudstack management-server :/
And "ip a" tell me cloudbr0 is down...
So, there is a real difference between :
- create the networking configuration with "nmcli command" and add
"nm_controlled=no"
- create the networking configuration manually and directly with
"nm_controlled=no"

Hi Nicolas,
First of all – you learn something new every day – I didn’t realise
there was a difference between a team and a bond – but there is:
https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/7/html/networking_guide/sec-comparison_of_network_teaming_to_bonding
So with regards to this – I can’t comment – suggest you test with both, but I
would expect teaming to work just as well looking through the comparison table
above.
I may be missing something – but to me it looks like your main problem
is this:
eth0/eth1 ---X---> teamed NIC (mgmt) --> cloudbr0
i.e. you have eth0 and eth1 – but they are not linked to the team in
any way – I would expect to see a master/slave type configuration in your
ifcfg-* files. The odd thing here is obviously that you can ping the host and
speak to it in the first place – which would point to cloudbr0 somehow being
online – hence my suspicion may be wrong.
With regards to nmcli – personally this has caused me too much trouble
through the years – hence I never use it and just mark my interfaces as
NM_CONTROLLED=no.

Dag Sonstebo

Hi Nicolas,
OK I’m with you. Sounds like you have an underlying network issue
on your KVM host.
Can you post up an ifconfig / ip a from your KVM host?
Can you also post up the contents of the ifcfg-eth0 + ifcfg-eth1 as
well as as ifcfg-<team or bond0> and ifcfg-cloudbr0?
Regards,

Hello Dag and Andrija,
Thanks for your answer,
@Andrija, we are using advanced zone and yes, we have specified
the traffics label and the agent on the host has retrieved the informations.
@Dag, its the documentation i followed, just, instead of bond i
used team NIC.

Hi Nicolas,
what does your zone networking look like ?
For every network you setup in the Zone (are you using
advanced zones, vlan
isolation method ???) you need to specify "KVM traffic

actually tells ACS what parent interface to look for...
