Hi all,
I'm aware that it is possible to plug pre-created macvtap devices to
libvirt guests - tracked in RFE [0].
My interpretation of the wording in [1] and [2] is that it is also
possible to plug pre-created tap devices into libvirt guests - that
would be a requirement to allow kubevirt to run with less capabilities
in the pods that encapsulate the VMs.
I took a look at the libvirt code ([3] & [4]), and, from my limited
understanding, I got the impression that plugging existing interfaces
via `managed='no' ` is only possible for macvtap interfaces.
Would you be able to shed some light into this ? Is it possible on
libvirt-5.6.0 to plug pre-created tap devices to libvirt guests ?

This links to the following message, which illustrates how to use pre-create
tap and macvtap devices:

Laine: it would be useful to add something like this short guide to the
knowledge base docs
