[ovirt-users] hosted-engine deploy 4.2.1 fails when ovirtmgmt is defined on vlan subinterface

[Kuko Armas]

I'm not sure if I should submit a bug report about this, so I ask around here first...
I've found a bug that "seems" related but I think it's not (https://bugzilla.redhat.com/show_bug.cgi?id=1523661)

This is the problem:

- I'm trying to do a clean HE deploy with oVirt 4.2.1 on a clean CentOS 7.4 host
- I have a LACP bond (bond0) and I need my management network to be on vlan 1005, si I have created interface bond0.1005 on the host and everything works
- I run hosted-engine deploy, and it always fails with

[ ERROR ] fatal: [localhost]: FAILED! => {"attempts": 50, "changed": true, "cmd": "ip rule list | grep ovirtmgmt | sed s/\\\\[.*\\\\]\\ //g | awk '{ print $9 }'", "delta": "0:00:00.006473", "end": "2018-02-15 13:57:11.132359", "rc": 0, "start": "2018-02-15 13:57:11.125886", "stderr": "", "stderr_lines": [], "stdout": "", "stdout_lines": []}
[ ERROR ] Failed to execute stage 'Closing up': Failed executing ansible-playbook

- Looking at the ansible playbook, I see it's trying to look for an ip rule using a custom routing table, but I have no such rule

[root at ovirt1 ~]# ip rule
0:      from all lookup local 
32766:  from all lookup main 
32767:  from all lookup default 

- I also find that I have no "ovirtmgmt" bridge

bridge name     bridge id               STP enabled     interfaces
;vdsmdummy;             8000.000000000000       no
virbr0          8000.525400e6ca97       yes             virbr0-nic
                                                        vnet0

- But I haven't found any reference in the ansible playbook to this network creation.

- The HE VM gets created and I can connect with SSH, so I tried to find out if the ovirtmgmt network is created via vdsm from the engine
- Looking at the engine.log I found this:

2018-02-15 13:49:26,850Z INFO  [org.ovirt.engine.core.bll.host.HostConnectivityChecker] (EE-ManagedThreadFactory-engine-Thread-1) [15c7e33a] Engine managed to communicate wi

rk configuration with VLAN-ID (1005), which is different from data-center definition (none).
2018-02-15 13:49:30,302Z ERROR [org.ovirt.engine.core.bll.hostdeploy.InstallVdsInternalCommand] (EE-ManagedThreadFactory-engine-Thread-1) [15c7e33a] Exception: org.ovirt.eng
ine.core.bll.network.NetworkConfigurator$NetworkConfiguratorException: Failed to configure management network

- So I guess that the engine tried to create the ovirtmgmt bridge on the host via vdsm, but it failed because "Host ovirt1 has an interface bond0.1005 for the management netwo
rk configuration with VLAN-ID (1005), which is different from data-center definition (none)"
- Of course I haven't had the opportunity to setup the management network's vlan in the datacenter yet, because I'm still trying to deploy the Hosted Engine

Is this a supported configuration? Is there a way I can tell the datacenter that the management network is on vlan 1005? Should I file a bug report?
Is there a workaround?

Salu2!
