Hi Didi=2C
I can confirm that using both an ovhe-answers.conf directive:
OVEHOSTED_NETWORK/firewallManager=3Dstr:nonexistent
and an /etc/ovirt-host-deploy.conf.d/99-prevent-iptables.conf with:
[environment:enforce]
NETWORK/iptablesEnable=3Dbool:False
results in "ovirt-hosted-engine-setup --config-append=3Dovhe-answers.conf" =
leaving iptables rules untouched while adding the second hypervisor host to=
an already deployed self-hosted-engine with one physical host.
Many thanks again=2C
Giuseppe
PS: is there any difference in using "ovirt-hosted-engine-setup" vs.
"hoste=
d-engine --deploy" ?

Hi Didi=2C
many thanks for your invaluable help!
I'll try your suggestion (/etc/ovirt-host-deploy.conf.d/99-prevent-iptables=
.conf) asap and then I will report back.
By the way: I have a really custom iptables setup (multiple separated netwo=
rks on hypervisor hosts)=2C so I suppose it's best to hand tune firewall ru=
les and then leave them alone (I pre-configure them=2C so the setup procedu=
re won't be impeded in its communication needs anyway AND I will always gua=
rantee the most stringent filtering possible with default deny ecc.).
Many thanks again=2C
Giuseppe

Hi Didi=2C
I found the references to NETWORK/iptablesEnable in my engine logs (/var/lo=
g/ovirt-engine/host-deploy/ovirt-*.log)=2C but it didn't seem to work after=
all.
Full logs attached.
I resurrected my Engine by rebooting the (still only) host=2C then restarti=
ng ovirt-ha-agent (at startup the agent failed while trying to launch vdsm=
=2C but I found vdsm running and so tried manually...).
OK=2C so it's host-deploy that's doing that.But it's not host-deploy itself=
- it's the engine that is talking to it=2C asking it to configure iptables=
.I don't know how to make the agent don't do that. I searched a bit the sou=
rces (which I don't know)and didn't find a simple way.
You can=2C however=2C try to override this by:# mkdir -p /etc/ovirt-host-de=
ploy.conf.d# echo '[environment:enforce]' > /etc/ovirt-host-deploy.conf.d/9=
9-prevent-iptables.conf# echo 'NETWORK/iptablesEnable=3Dbool:False' >>
/etc=
/ovirt-host-deploy.conf.d/99-prevent-iptables.conf
Never tried that=2C and not sure it's recommended - if it does work=2C it m=
eans that host-deploy will notupdate iptables=2C but the engine will think =
it did. So it's better to find a way to make the engine not dothat. Or=2C b=
etter yet=2C that you'll explain why you need this and somehow make the eng=
ine do what you want...-- Didi
