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.

Objet : Re: host KVM unable to find cloudbr0
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,
Dag Sonstebo

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.
Best regards,
N.B

Hi Nicolas,
Take a look at the following blog article – it’s a couple of years old

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 label" - this
actually tells ACS what parent interface to look for...
