Hi,
I am new to openvswitch, and while experimenting, I built a mixed setup :
- two xenserver (XCP 1.1.0) with openvswitch : xcp-1 and xcp-2
- one ubuntu 10.04 with openvswitch (1.2.2) : bm-1
I was able to build two networks on xenserver and connect them through a GRE
tunnel
I cannot add the ubuntu machine to the same network.
My goal is to build something like :
xcp-1 <----gre----> xcp-2 <-----gre------> bm-1
xcp-1, xcp-2, and bm-1 are all on 172.16.228.x.
I would like to create a private network on 192.168.200.x between VMs in xcp-1,
xcp-2 and the bm-1 server
Here are my questions :
-in the following setup, how (why) are incoming GRE packets directed to the
xapi2 bridge ?
on xcp-1 :
xenbr0 is administrative interface with an IP (172.16.228.201)
[root@xcp-1 xen-vms]# ovs-vsctl list-ports xenbr0
eth0
vif1.0
xapi2 is the VM bridge with the tunnel
[root@xcp-1 xen-vms]# ovs-vsctl list-ports xapi2
gre0
vif3.0
tunnel was created through the command :
ovs-vsctl add-port xapi2 gre0 -- set interface gre0 type=gre
options:remote_ip=172.16.228.196
corresponding tunnel was created on xcp-1 with :
ovs-vsctl add-port xapi1 gre0 -- set interface gre0 type=gre
options:remote_ip=172.16.228.201
- what is the right setup to add bm-1 to the same network ?
I tried to tunnel between xapi1 on xcp-2 and bm-1:
[root@xcp-2 ~]# ovs-vsctl list-ports xapi1
gre0
gre1
vif1.1
vif4.0
gre1 was built with the following command:
[root@xcp-2 ~]# ovs-vsctl add-port xapi1 gre1 -- set interface gre1 type=gre
options:remote_ip=172.16.188.200
I tried to replicate the xenserver setup on bm-1 by adding a bridge with eth0
as a port, adding another bridge with the tunnel and an interface, but it has
not been successful (i tried also with only one bridge with the tunnel and an
interface). Ideally, on bm-1 I would like to have two interfaces, one on
172.16.188.x and one on my private network (192.168.200.x)
Thanks in advance,
JC
