[ovs-dev] Doubt regarding packet registers
Hi, I would like to know the difference in behavior between metadata field and packet register. Is register a per-packet entity like metadata field? If there is an action to copy metadata value to a packet register, will there be any performance impact on the packet processing pipeline, since each packet matching on this flow has to access the register sequentially?

Thanks Ben! The last question is not valid if the answer to first question is Yes.

[ovs-dev] Applying QoS on Logical Ports
Hi, Can QoS be applied on any logical ports, say for example : patch ports or tunnel ports? Thanks, Faseela ___ dev mailing list dev@openvswitch.org http://openvswitch.org/mailman/listinfo/dev
Re: [ovs-dev] Applying QoS on Logical Ports
Hi, Thanks for the information. What will be the best way to implement hierarchical qos in this case?

[ovs-dev] Doubt regarding openvswitch UUID
Hi, I have two OVS running on two VMs. Since both the VMs are based on the same template, both vSwitches are getting the same UUID. I need separate UUIDs for the usecase I am trying out. Is there any way I can manually set the vSwitch UUID to non-conflicting values? Thanks, Faseela ___ dev mailing list dev@openvswitch.org http://openvswitch.org/mailman/listinfo/dev
Re: [ovs-dev] Doubt regarding openvswitch UUID
I tried removing the conf.db and restarting the VM, was able to get a new UUID... -Original Message- From: Ben Pfaff [mailto:b...@ovn.org] Sent: Tuesday, November 24, 2015 12:14 PM To: Faseela K Cc: dev@openvswitch.org Subject: Re: [ovs-dev] Doubt regarding openvswitch UUID On Mon, Nov 16, 2015 at 05:26:33PM +, Faseela K wrote: > I have two OVS running on two VMs. > Since both the VMs are based on the same template, both vSwitches are > getting the same UUID. > I need separate UUIDs for the usecase I am trying out. > Is there any way I can manually set the vSwitch UUID to non-conflicting > values? If it's OK to start with an empty database, you can just delete the database and restart OVS, because the usual init scripts will create the database if it's empty. ___ dev mailing list dev@openvswitch.org http://openvswitch.org/mailman/listinfo/dev
