Hi Raja, So yes I tried to turn off the checksum offload in the VMs and of course it works. I tried with several images (fedora, ubuntu, debian) with different kernels. I'm using a two month old contrail master branch deployment. I'm going to deploy an up to date master version today in order to confirm the issue.
Thanks, - Sylvain ----- Original Message ----- From: "Rajagopalan Sivaramakrishnan" <[email protected]> To: "Sylvain Afchain" <[email protected]>, [email protected], "Prasad Miriyala" <[email protected]> Sent: Thursday, September 17, 2015 7:53:40 PM Subject: Re: [opencontrail-dev] Partial checksum issue with mirror SI Hi Sylvain, Does it work when you turn off checksum offload inside the VMs (using ethtool)? What image are you using for the SI VM? Which Contrail release are you using?
