The features for sfc/nsh are not installed so pretty sure nothing is trying to use nsh. Can you look again at the two exceptions to see if that is correct? OVS 2.8.0 added userspace NSH support, with more support added in 2.8.1 and 2.8.2. I see the ofp csit is using 2.8.1. it has deserialization errors but not the same as the netvirt csit. ovs 2.8.2 says it moved the NSH support to the standard spec support so maybe that is why it is causing more problems that 2.8.1? > We already have patches pushed by Jamie to implement these new NSH fields > and remove the old one, hopefully that should fix it. > How far along are these patches? > > On Sun, Jul 8, 2018 at 5:26 AM Sam Hague <[email protected]> wrote: > >> Adding Daya to see if they have been doing any testing with ovs 2.8.2 or >> later.
