I have two interfaces on my machine, eth0 and eth1.
I created two OVS bridges, vmbr0 and vmbr1.
vmbr0 has an intport with my local ip for management (10.0.0.21)
vmbr1 has no intports, and no ip address configured.
Likewise, the physical interfaces have no ip addresses defined.
However, vmbr1, which is connected to a network where dhcp is served, receives an ip address, as does the eth1 interface.
So, I redid my network config as displayed below, and for the time being, disabled vmbr1 and eth1 connections (to simplify troubleshooting)
It turns out vmbr0 and eth0 are ALSO getting extra dhcp assignments.
What is causing this? It seems like the inet manual option is being ignored.
/etc/network/interfaces
ip addr
As you can see, intpt is getting the static IP I set (10.0.0.21), but it's also picking up another IP via dhcp (10.0.0.202).
You can also see vmbr0 itself, despite being set to inet manual (no ip), is getting an IP assigned (10.0.0.129).
Configuration was done all via gui. The only thing that has an IP set is intpt. Everything else should NOT be getting an IP.
