[ovirt-users] Hosted engine notifications don't work after upgrading ovirt from 3.5 to 3.6

[Martin Sivak]

Hi Stefano,

we haven't touched the code for this, but I see that also. If you are
willing to experiment just a bit (it is revertable) you can apply the
attached patch to
/usr/lib/python2.7/site-packages/ovirt_hosted_engine_ha/broker/notifications.py.
It seems to solve this for me.

diff --git a/ovirt_hosted_engine_ha/broker/notifications.py b/ovirt_hosted_engin

                         to_addresses,

Then restart the ovirt-ha-broker service.

In any case, please open a new bug so we can properly fix it in the
nearest 3.6 update.

Regards

Martin Sivak
