Hello all

Miguel (in CC) and I have been working on adding macvtap support to Kubevirt. This allows setting up a macvtap interface for a VM that is directly attached to one of the node interfaces.

Why?

Macvtap interfaces are commonly used to simplify bridged virtualized networking. In the case of Kubevirt, the benefit is two-fold; it not only simplifies the networking at host level, but also at pod level, avoiding the extra bridge setup required there in a standard setup.

How?
