setup open vswitch

[Airidas]

Hello guys,

I'm new in openvswitch. Please help me set up openvswitch.

I have 1 host with 2 physical network adapters and 3 virtual machines.
Now network setup is:
bond0 type=linux bond port/slaves=eth0 eth1 no IP address
vmbr0 type=linux bridge port/slaves=bond0 IP address=192.168.1.12

Virtual machines should communicate each other through virtual switch and communicate with real network.

How to configure the network?

Thanks.

Hello Airidas

1. install openvswitch - important: /etc/apt/sources.list must contain "deb http://download.proxmox.com/debian wheezy pvetest" - by

apt-get install openvswitch-switch

Following steps by WEB-GUI:

2. If you continue using existing physical NICs at host and IP address: remove IP-address and ports from vmbr0

3. create an ovs bridge e.g. vmbr1(no ports for the moment) and assign the desired IP address, probably 192.168.1.12, activate autostart too

4. create an ovs bond with slaves eth0 eth1 (I suppose) and select as bridge vmbr1

5. assign the virtual NICs in the VMs to vmbr1

6. reboot

You can verify after reboot the proper configuration by

ovs-vsctl show

should show your configuration (bridge, ports), version must be 2.0.90 or higher

Kind regards

Mr.Holmes

could you please explain why doing a ovs bridge first and then a ovs bond.

woulden't be enough to do a ovs bond and add the eth0 and eth1?

Thanks for your teaching
have a nice day

When I make in WEB-GUI "Create" -> "OVS Bond" the field "OVS Bridge" is obligatory. That means the OVS Bridge has to be configured first.

I didn´t think to much why - because it wasn´t a problem for me to follow this. Note: In real life both is set up at the same time - in fact after the next reboot (or manual change of /etc/network/interfaces and /etc/init.d/networking restart)

Mr. Holms
i tryed and seems to work

:~# ovs-vsctl show
39a05a68-ac9d-4695-ae00-6520ac1ba018
Bridge "vmbr1"
Port "bond0"
Interface "eth1"
Interface "eth0"
Port "vmbr1"
Interface "vmbr1"
type: internal
ovs_version: "2.0.90"

on Point3 i added a 192.168.14.12, 255.255.255.0, 192.168.14.1 (IP; Subnetmask, Gateway) too. Hope this is correct

have a nice day

Basicly it would work....
But as soon i upload the IOS a got a slow connection, if i do deconnect a link it go fast.
I Belive the Problem is not to be able to configure the ports of my cisco rv016 and FritzBox.
have a nice day

hello, the slow connection whas because the used a balance feature which was not supported by my Switch ;'-)

 

[vikozo]

hello
if the ovs_version: "2.0.90" is higher is it a problem?
have a nice day
