Hi Frank, this is a setup that *should* work. A few questions/thoughts:
- You should not have an IP address assigned to enp0s3, which I'm assuming is
the physical interface in this VirtualBox VM. And the link status for this
interface is up, yes?
- In addition to assigning an IP address to mgmt0, make sure you actually set
the mgmt0 interface to up ("ip link set mgmt0 up", if memory serves correctly).
- Stupid question, I know, but you're sure that the VirtualBox networking
configuration isn't getting in the way, right?
- Using "ovsbr0" instead of "mgmt0" is functionally equivalent, as far as I
know. The fact that assigning an IP address to ovsbr0 works but mgmt0 doesn't
work leads me to believe the issue is with the configuration/operation of the
mgmt0 interface.
