Re: [ovs-dev] Native tunneling on DPDK

I meant how can you assign an IP address to an *userspace* bridge (not kernel bridge) if I didn't state that clearly enough. Thanks, Tim At 2015-02-16 23:06:44, "Tim Deng" wrote: >Hi Pravin, > >I'm trying to setup user space tunneling over DPDK, but I cannot follow >the instruction of Example

[ovs-dev] [help]Linux kernel panic happened, and find skb->protocol is 8.Is anybody ever had the same situation before?

Here is the problem. I have a network system as flows: It has vlan & vxlan on it, and between every two vms, they send tcp&udp. After this linux system runs 14 days later, a kernel panic happened. Then I analyze Linux kernel crash dumps with crash. Here is the result: crash> bt PID: 3323 TASK:

I agree with Kevin that we should adopt veth pairs for fixing the issue in the short term, at least until CT gets merged and distributed in OVS. At that point the transition to a OVS based solution will make a lot of sense, given that the numbers show that it's worth of course ;) On Sun Feb 15 201

Hi Pravin, I'm trying to setup user space tunneling over DPDK, but I cannot follow the instruction of Example procedure #1 in README-native-tunneling.md: -"...assign ip address (172.168.1.1/24) to br-eth1..." How can you assign an IP address to a bridge interface? Thanks, Tim __

Nithin, in a NEW NL command, when the WFP filter needs to be created for a new tunnel port, the code runs at dispatch IRQL. At dispatch IRQL any WFP call fails. That is why I have created a thread for postponing WFP-based work when the IRQL is lowered at passive level and the WFP calls can be su
