Dear all,
I'm using ovirt 4.3.2 with its engine on a virtual machine. The nodes
are all Centos 7.7.
Is this a hosted-engine?
Both engine and hypervisor systems work on a 10.0.0.0 private
network.
Now I would like to let users access the ovirt web page (user portal)
and for this
I must necessarily add a second network interface to the engine by
inserting a public ip. I can't use NAT.
Can you give me any advice for this operation ?
Can I add the network interface and then run engine-setup ?
Will oVirt be accessible from both ip addresses at the end of this
operation ?
Generally speaking:
1. You should be able to add an IP address to the existing NIC. If this
is a hosted-engine, this might be simpler than adding a NIC. Of course,
this might not be relevant in your case, depending on network topology,
conf, etc.
2. The engine itself does not care at all about which IP addresses are
used to connect to it. Neither is httpd that is running there as a frontend
to it - it listens on all addresses. So just add the address somehow, perhaps
restart httpd if needed (but I do not think so), and everything should work.
3. The engine _does_ care about the _name_. So make sure you use the
existing name. For this, you'll have to change your DNS, or /etc/hosts,
as applicable.
4. If it's complex for you to keep the existing name (e.g. because you want
to make it work from both old and new addresses, etc.), you can also add
another name that the engine will agree to be connected to, using
SSO_ALTERNATE_ENGINE_FQDNS, see e.g. [1].

Lots of thanks.
