I've attached the output of the ansible command as a log file, this is what happens when the IF bond0.910 is assigned the IP and `ovirtmgmt` is not defined on the host.

according to the logs ovirtmgmt is still there.

can you please share the output of 'ip a'?

Dear Simone,

This is my experience too, but I'm now hitting this error on the hosted-engine install at the part where it registers the hypervisor as the first host in the engine:

e.bll.network.NetworkConfigurator$NetworkConfiguratorException: Interface ovirtmgmt is invalid for management network

The host's ovirtmgmt network connection is a statically assigned IP on a VLAN on a bond, how should I be configuring this if not manually?

If you need to deploy over vlan 123 over bond0 simply configure a device exactly called bond0.123 and statically configure your IP address there.

Choose it for hosted-engine deployment, nothing more: ovirtmgmt will be automatically created over that device and the vlan ID will be set at engine level for the whole management network.

 

Regards,

Callum

It's ok, migrating to 4.3.2 on the oVirt node (from 4.3.0) did the job of fixing it.

It is a bug if you intend on using the ovirtmgmt network to deploy your ansible from

This is a bit tricky: when the engine brings up the host it also creates the management bridge and this could lead to a temporary network down on the selected interface for the bridge creation time (a couple of seconds?)

I tried it on a LAN and ansible ssh connection always survived but I 'm not sure it's always true.

 

, and you need it to have an IP address already on that range! But - it works as expected with the ovirtmgmt bridge setup so nothing to worry about.

Callum

Dear All,

We're trying to deploy our hosted engine remotely using the ansible hosted engine playbook, which has been a rocky road but we're now at the point where it's installing, and failing. We've got a pre-defined bond/VLAN setup for our interface which has the correct bond0 bond0.123 and ovirtmgmt bridge on top but we're hitting the classic error:

Failed to find a valid in

terface for the management network of host virthyp04.virt.in.bmrc.ox.ac.uk. If the interface ovirtmgmt is a bridge, it should be torn-down manually.

Does this bug still exist in the latest (4.3) version, and is installing using ansible with this network configuration impossible?

I don't think it's a bug; please avoid manually creating ovirtmgmt and simply set:
he_bridge_if: "bond0.123", in ansible variable file and the management bridge will be created for you at host-deploy time.

 

Regards,

Callum
