As you noticed, the use of vxlan would avoid having a complex network
But LinuxBridge is also compatible with VXLAN.
It can support unicast VXLan if l2pop is enabled, and work the same way OVS
does, but with l2pop improvements.
So if Linuxbridge becomes the default, maybe the good path would be
ML2+VXLAN+l2pop+LinuxBridge. This is one of the config I use, and it works
perfectly well, without having to reconfigure my network fabric, or even my
devstack node network config.
