[ovirt-users] oVirt 3.5 & NAT

[Phil Daws]

Thanks Dan & Antoni:

I wonder then if I could replace the standard libvirt defined network with an OpenVSwitch one like I have on my dev system?  That is just straight KVM with OVS integrated.  Maybe a bit more overhead in administration but possibly less than having to spin up a Neutron Appliance.

Unfortunately, this is not yet available "out of the box". You need to
create the natted network in libvirt, and then connect your vNic to it
via a vdsm hook.

This mailing list has seen various suggestions on this subject (such as
[1]). While searching for them, I found a recent blog using the extent
hook for that[2] (ymmv).
