Re: [ovirt-users] Problem with Neutron + Ovirt 3.5.1 [Centos 7]
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?

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?
