Hi Daniel,


> For Juno the vif_driver option still exists & can be used.

In the current master branch, there is no 'vif_driver' option for libvirt.
It has been deleted by [1], and I can't find any patches to enable 'vif_driver' config on gerrit.
Is there plan to get the 'vif_driver' config available before the Juno release?
