I have sent a patch to upstream, and wait for developers review: https://www.redhat.com/archives/libvir-list/2011-July/msg00859.html Alex sent patch, waiting for review: https://www.redhat.com/archives/libvir-list/2011-July/msg00966.html Even though I've sent patch, now that I am re-thinking this over again I don't think this is okay with libvirt policy. I mean, it's possible to have persistent domain, start it and undefine while running (=> transfer to transient domain). Therefore in fact, we want to make undefine on active device/interface possible. But I must admit that libvirt doesn't know anything like transient interfaces yet. And that's where I see the fix should aim. Introducing transient interfaces to libvirt. Thoughts? Setting condNak design meanwhile. transient interfaces probably requires heavy netcf coordination, and given that netcf is basically maintenance mode at this point I doubt this will ever be fixed as suggested in Comment #5. closing |
