As said, I'm open to integrate the gui also, with a "experimental" title
and if only shown once pve-network is installed. This way you'd reach a
lot more people open for testing easier, as it does not requires them to
apply patches and build packages them self or download unsigned packages :)

me too, ideally pve-network would replace the crude OVS implementation completely
and allow to depreacate it some time in the future (wishful thinking, I know ^^)
