[ovs-discuss] [opnfv-tech-discuss] Persistent error when trying to install Devstack+OVN

[Numan Siddique]

Hi Amir,

In order for devstack to not compile ovs kernel module,  you can set
"OVN_BUILD_MODULES=False" in your devstack local.conf file. The openvswitch
kernel module from the centos 7 would be used.

The compilation error definitely needs to be resolved though.

Thanks
Numan
