well, honestly I did that (modified ifcfg and then use nmcli con
reload). So right way is using nmcli con modify command?
Yes or nmstate. Just be aware that anything that you do to interface
outside of oVirt can have harmful impacts on the host and overall oVirt
state.

just for sure - do you mean on the live host which hosts running HE vm
or on a new installation?
The installation won't work because we enforce MAC under these conditions:
1) The bond exists
2) The bond is owned by vdsm and MAC is specified in config (This is the
case when you try to update the bond)
or the bond is not owned by us (Installation process)
This is basically to make sure that we preserve the MAC address that was
set.
The only option that I see right now is to remove the bond from running
host through oVirt and create it again with active-backup=1.
This is not a perfect solution as any further change to this bond will
automatically end up in the categories above.
well, I ended in state where oVirt thinks that ens5 is used outside of
bond0. It happended probably when I tried to break bond0 and setup ens5
witch at least ovirtmgmt network to not to loose access (it failed too
with "Invalid Network name").
see http://mirror.slu.cz/tmp/ovirt_setup_network.gif
It looks like oVirt manager setup network section is not much BFU proof ;-)
well, I am stucked now. I will try to reinstall one host but without
prepared bond interface and will try to setup bond completly in oVirt.
...but after lunch ;-)
Cheers,
Jiri
Hopefully this helps.
Thanks,
Ales
It looks like there is the same o similar bug while installing hosted
engine via ovirt-hosted-engine-setup. I tried it many times yesterday
and installation failed with the same error
[ ERROR ] fatal: [localhost]: FAILED! => {"changed": false,
"msg": "The
host has been set in non_operational status, deployment errors: code
505: Host ovirt-hci01.stud.slu.cz <http://ovirt-hci01.stud.slu.cz>
installation failed. Failed to
configure management network on the host., code 1120: Failed to
configure management network on host ovirt-hci01.stud.slu.cz
<http://ovirt-hci01.stud.slu.cz> due to
setup networks failure., code 9000: Failed to verify Power Management

HostSetupNetworksVDS failed: Internal
JSON-RPC error: {'reason': 'MAC address cannot be specified in bond
interface along with specified bond options'}, fix accordingly and
re-deploy."}
My workaround was to remove fail_over_mac=active option during
install :-)
