Nice to hear

I suspect that this is a side effect of this bug:
https://bugzilla.redhat.com/1322849
Under certain circumstances we could have a mismatch between the host
id as saw by ha-agent and the spm_id used by the engine.
Can you please execute this query
SELECT vds_spm_id_map.vds_spm_id, vds.vds_name FROM vds_spm_id_map,
vds WHERE vds_spm_id_map.vds_id = vds.vds_id;
to check the spm_id of your host in the DB comparing its output with
the output of
grep host_id /etc/ovirt-hosted-engine/hosted-engine.conf
run on each involved host?
If you find any mismatching id you have to change
/etc/ovirt-hosted-engine/hosted-engine.conf to reflect the engine
spm_id and reboot the host.
