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

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

Hi Eduardo,
May I ask for more details on what you're testing exactly? You're
running "oVirt" VMs? And do these VMs use "external" networks (i.e.
networks that were configured on the Neutron server)?

What do you mean by "private"? It does have an IP address that's
accessible from the other host, right?

Hello, Lior.
Thx for replay.
You're running "oVirt" VMs?
Yes my vm running on oVirt.
VM2 with ip: 192.168.100.7 running on ovirt2 (neutron external network
extnet)
VM1 with ip: 192.168.100.6 running on ovirt1 (neutron external network
extnet)
And do these VMs use "external" networks (i.e.
networks that were configured on the Neutron server)?

Hi Eduardo,
May I ask for more details on what you're testing exactly? You're
running "oVirt" VMs? And do these VMs use "external" networks (i.e.
networks that were configured on the Neutron server)?

What do you mean by "private"? It does have an IP address that's
accessible from the other host, right?

Thanks Eduardo. So it seems from your tcpdump that the Neutron bridge is
correctly sending ARP requests. What happens then on bond1 and in your
switch?
