Good night,

I'm trying oVirt 3.5 + neutron appliance in BareMetal servers, but I am
facing some problems.

structure:

2 servers with:

oVirt 3.5.1
hundreds 7
4 network adapter
      int = 0 + int2 bond0 => public network => ovirtmgmt
      int = 1 + int3 bond1 => private network => neutron

Virtual Appliance Neutron:

NOTE: All steps were followed, and checked several times.

Openvswitch configuration:

*Testing:*
Connectivity between my virtual machines only work when both are running on
the same node, when virtual machines are running on different hosts can not
make a machine ping the other.

*Tcpdump:*
