[ovirt-users] "Cannot acquire bridge address" / Failure in "hosted-engine --deploy" on 4.1.8

[Frank Wall]

Hi,

when running "hosted-engine --deploy" on a fresh CentOS 7.4 with pre-built
network configuration (and ovirtmgmt bridge), the following error occurs:

2017-11-27 19:08:12 DEBUG otopi.context context._executeMethod:142 method exception
Traceback (most recent call last):
  File "/usr/lib/python2.7/site-packages/otopi/context.py", line 132, in _executeMethod
    method['method']()
  File "/usr/share/ovirt-hosted-engine-setup/scripts/../plugins/gr-he-common/network/bridge.py", line 295, in _get_hostname_from_bridge_if
    raise RuntimeError(_('Cannot acquire bridge address'))
RuntimeError: Cannot acquire bridge address

While checking the source of bridge.py line 295 the root cause is interesting:

Running "vdsClient -s $HOSTNAME getVdsCapabilities" works perfectly, all NICs
and bridges are returned, but only "networks" is returned as empty list: {}.
Clearly looks like a bug. How can I resolve this issue?

ovirt-hosted-engine-setup-2.1.4-1.el7.centos.noarch
vdsm-4.19.40-1.el7.centos.x86_64
