Hi,
I'm migrating off a vmware-server infrastructure and one thing that
provided was a NAT and a HostOnly network by default. I'm trying to
replicate this (at least the NAT part) in ovirt.
A few years ago people were asking about setting up oVirt with
NAT/Internal networks, e.g.
http://lists.ovirt.org/pipermail/users/2012-April/001751.html
I also found
https://www.ovirt.org/develop/developer-guide/vdsm/hook/network-nat/
Has this at all been integrated in the intervening years? Or is NAT
networking still completely a manual process? One would think this would
be a relatively common interface, where you want to have a VM that isn't
directly connected to the internet but still has internet access via a
(virtual) NAT?
I'm afraid that we have not advanced this any further.
Main conceptual problem with the suggested manual process is that VMs
behind NAT cannot be reliably migrated to another host.
I hope that our current work, of attaching VMs onto an OVN-defined
overlay network (see
https://www.ovirt.org/blog/2016/11/ovirt-provider-ovn/ ) would satisfy
most of what you need of a NATted network, and more.
For HostOnly networks, btw, you can create dummy interfaces

and then attach them to a network.
