I don't think the guest agent ip information should be correlated to the vnic engine information at rest api level. the vm (and vnic) api provides the authoritative configuration information of the guest as defined in the engine. I don't think we should 'taint' it with untrusted data from the guest. it would make sense to place there IPs configured/allocated by engine when we deal with ip allocation though.

i.e., the guest info element in the rest api provides good separation between engine level data, and guest agent data. _______________________________________________ Engine-devel mailing list Engine-devel(a)ovirt.org http://lists.ovirt.org/mailman/listinfo/engine-devel
