------- Comment From gowrishanka...@in.ibm.com 2016-10-03 10:23 EDT------- Interesting. I ensured that, ovs and kernel upto date, but of no luck. OVS backed virtual nic still fail to establish tcp with tx on. Here is xml for this port:
<interface type='bridge'> <mac address='52:54:c1:a2:7c:53'/> <source bridge='ovsbr0'/> <virtualport type='openvswitch'> <parameters interfaceid='6b0499e1-42d5-4afa-ae66-9d403aba30ac'/> </virtualport> <model type='virtio'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x03' function='0x0'/> </interface> Wrt your xml, I don't think having a dhcp network as you have is anything of concern for the root cause as it is about csum that breaks the session. pkg info: openvswitch-common 2.6.0-0ubuntu1 linux-generic 4.8.0.17.27 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1629053 Title: ovs bridge breaking TCP between two virtio net devices when checksum offload on To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/openvswitch/+bug/1629053/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
