We have two issues here. First is that
https://gerrit.ovirt.org/gitweb?p=ovirt-hosted-engine-ha.git;a=blob;f=ovirt_hosted_engine_ha/lib/storage_backends.py;h=f2fbdc43d0e4afd7539a3a1de75de0cb07bdca9d;hb=HEAD#l271
is still using vdscli to contact vdsm, instead of the preferred
jsonrpccli.

The second is that vdscli.connect's heuristic ends up reading the local
server address from vdsm config, where it finds the default ipv6-local
address of "::".

Please try setting

[addresses]
management_ip='0.0.0.0'

in your /etc/vdsm/vdsm.conf instead of the crontab hacks.


Would you please open a bug about the two issues
(ovirt-hosted-engine-ha and vdsm networking)?

Would you report the output of `netstats -nltp` on your host, as I do
not completely understand why no interface (not even the loopback one)
was listening on ipv6?

Dan.
