Subject Re: OVS Plugin does not appear on the Network Service Providers screen

I remember that if you want to use GRE for network isolation, you should select GRE instead
of VLAN when creating the physical network of zone

Hi Jerry,

thank you for your answer.

I created the zone with VLAN on both cloudbr0 and cloudbr1 (I am following this guide
and the two KVM hosts are now working.

BUT I don’t see the GRE tunnel created in the openvswitch. To further check I created two
VM instances the first on host1 and the second on host2. The router is on host2 and the instance
on this host gets ip form the dhcp, but the vm instance on the host1 cannot communicate with
the router because it is on the host2 and no GRE tunnel exists between the hosts.

Should I create the tunnel manually?… Is this the nornal procedure? … if yes, should I
create a seperate bridge for this or use an existing bridge e.g. cloudbr1 (public) ?
