[ovirt-users] Hosted-Engine with only 1-IP

[Martin Sivak]

Hi,

What are you trying to accomplish? Hosted engine is a special case
where the management is itself just a VM that can be migrated across
the cluster. But it does not make much sense when you only have one
server.

But to describe the requirements:

You should generally have a network subnet for all your hosts. The
hosted engine VM needs to be able to access it. The regular VMs do not
necessarily need it, but I guess they need some way to reach the
network if you want internet access.

The engine needs to talk to all virtualization hosts (nodes)
The engine also needs to have predictable IP address and dns name so
the nodes can reach it.
The admin needs to be able to connect to the engine and should be able
to connect to the VNC/spice console of all VMs.
The hosts need to be able to talk to each other, preferably on the L2 level.

I assume you might be able to use local network addresses for your
virtualization hosts, but that seems like a lot of tweaking to make it
right.

Regards
