Hello,
This patch series adds support for the MacVTap device driver in Ganeti.
As stated in the respective design doc, this implementation targets the
KVM hypervisor. It also includes some new unit tests to cover the new
NIC mode introduced and also it documents the new feature in the
relevant man pages.
Thanks,
Dimitris
