I've seen this bugzilla issue, but TBH I was a bit baffled. Back in the days
of oVirt 3.x it was *mandatory* to setup the bridge manually, now it's
unsupported. :D

Technically hosted-engine-setup was already using vdsm to create the management network in its 1.0 release

https://gerrit.ovirt.org/#/c/16716/

so I don't think we ever required to manually do it just for that purpose or at least not on common configurations.

I remember setting up a 4.0.x environment earlier this year and did not
experience this issue. And I couldn't find any information as to which release
introduced this (breaking) change.

Several places still talk about manually creating bridges, maybe it would
be a good idea to remove this dated documentation or add a hint that this
does not apply to the current release:

https://www.ovirt.org/documentation/how-to/networking/bonding-vlan-bridge/
(There might be more pages, I haven't done an extensive search.)

I'm absolutely with you on this: by the way that page still recommends to disable NetwokrManager which instead is not an issue today.
