Hi,
The -- has been dropped. I have verified that the following configuration
settings work (this was in a multinode Openstack setup using openvswitch):
libvirt_vif_driver = nova.virt.libvirt.vif.LibvirtOpenVswitchDriver
libvirt_vif_type = ethernet
linuxnet_interface_driver = nova.net
HI All,
I didn't find the details here to be correct:
http://openvswitch.org/openstack/documentation/
'--' is no longer used in nova.conf
e.g. '--libvirt_vif_type=ethernet' should be replaced by
'libvirt_vif_type=ethernet'
Not sure, if '--libvirt_ovs_bridge=br-int' is used anymore but I

Thanks,
You rock !

Hi,
I was using vlan command to give tag or make interface as trunk ports.
Ovs-vsctl set port eth0 trunks=2,3
1) Now if both machines physical inetrface are member of different vlan
then also CFM works.
2) I am putting my both machines on different subnet by providing different
subnet IPs

That's one way to do it, sure. Flows are pretty cheap. How big is
your N? I wouldn't hesitate to do it this way up to, say, N=100.

Nice trick, but does that mean we need n_links-1 rules for each source
on a switch running multipath routing?
for example suppose a switch is connected to four machines: M0 on port
0,M1 on port 1,M2,M3
I define this rules (loose syntax)
ovs-ofctl add-flow br0 action=multipath..,resubmit on table
A register, such as NXM_NX_REG0[], is one reasonable choice.
You can use "resubmit" along with a special OpenFlow table to map this
value to a destination.

Hum, thanks I have not read that in detail.
OK, still I have question: We store the output of multipath algorithm in
a field defined there, but which field should we use?
how the value of this field relates to the routing to the destination?

I just want an example that fills the action part in the following rule:
ovs-ofctl add-flow br0 nw_src=10.0.0.1/32,nw_dst=10.0.0.1/32,action=?
The manual page says:

Hashes fields using basis as a universal hash parameter,

It's all documented. Which part is troublesomee?
Thanks,

Open vSwitch implements a very small subset of the 802.1ag
specification. In a more sophisticated implementation, one would be
able to set the maintenance domain of the CFM module thus achieving
the separation you want. Unfortunately, Open vSwitch chooses it's own
maintenance domain which cannot

Oh. Perhaps Ethan can help you. I've forgotten how CFM worked in
1.2.

You'd have to add support in many places throughout the tree, because
OVS assumes Ethernet addressing and packet formats. I'd probably
start with lib/flow.[ch].

I would like to add this functionality in OVS.
Can you tell me what is the difficulty to do this work.

You mean, when a controller is not connected, you cannot see any echo
request messages? This should not be surprising, because the echo
request requires a controller connection.

hi,
I set max_backoff as 10 sec and then after every 10 sec i saw controller
status as *"connecting*" using
*ovs-vsctl list controller* command
but i can not see any echo request message being sent from switch to
controller ip after max_backoff interval is over.

G'day All,
I have used cfm configure between two ovs in different subnet (used the
subnet mask). CFM packets are successful transmitted between two ovs but as
per 802.1ag spec the MEPs in different domains do not connect to each other.
Same things are happening at different VLAN case also (MEPs a

I got some great responses to this last time, but thought I'd solicit more if
possible. Please consider responding, particularly if you use OVS in a
production environment.

Hi,
I worked on the ethernet interface with OVS and now I am interested in
working on infiniband interfaces
I want to know if the OVS Support Infiniband
if this is not the case, Are there any plans to support Infiniband in

Thanks in advance,

Hi,
I am using OVS 1.2.2 which is requiring cfm_remote_mpid value.
there is no cfm_remote_mpid(s) parameter in this.
now cfm working between 2 physical machine but when I am giving vlan tag 2
on first machine physical interface and vlan tag 3 on second machine
physical interface then also CCM pac
