@ExploreScience You've 3 options
- When OVS or OVN are installed from packages, they use the paths - /usr/share/, /var/log etc but when OVN is configured without specifying any prefix , it uses the paths - /usr/local/share, /usr/loca/var etc. So to fix this you can create a symbolic links like - ln -s /var /usr/local/var (This approach is hacky but works for simple testing)
- Configure OVN with "--prefix=/usr" . See this as an example - https://github.com/ovn-org/ovn-fake-multinode/blob/main/install_ovn.sh#L52
- Build OVN rpm packages . For fedora/centos you can do
- cd ovs
- make dist
- cd ..
- make rpm-fedora
Not sure how to generate packages for debian.

Please note OVN 20.12.0 require OVS master to build.
Once OVS 2.15 is released we can tag OVN to OVS 2.15. Until then OVS master is required to build.
Regarding runtime compatibility, can you the report the failures ?
OVN 20.09.0 and 20.12.0 should work fine with OVS 2.13.1.
Thanks

I hope OVN can have a clear compatibility list like Open vSwitch, thank you. My Open vSwitch turns on DPDK, And my guess is that the DPDK template in OVN is not compatible.

I think if you do make clean or make distclean and compile again (both for ovn and ovs) it should work.

@numansiddique After trying again, it still has no effect.I remove the --with-dpdk parameter and it works normally

Please see the reply from @igsilya here for a similar query - https://mail.openvswitch.org/pipermail/ovs-discuss/2023-July/052577.html
Qouting it here:
Hi, Joe.
The version of OVS to build with and version of OVS to run with
are two different things. You should build OVN with the version
of OVS provided in a submodule. For v22.03.2 it will be OVS
commit 2410b95597fcec5f733caf77febdb46f4ffacd27.
OVN only uses some libraries from OVS sources. You should be
able to run OVN built this way with your OVS 2.17.7 without any
issues.
One inconvenience though is that, unfortunately, release archives
on GitHub do not include submodules (GitHub doesn't support that).
So, you'll need to check it out yourself.
Best regards, Ilya Maximets.
You can compile OVN without enablin dpdk config in OVS.
Thanks

@numansiddique I have installed ovs from package. I use the submodule ovs of ovn to build ovn. But when I install ovn, and start_nothd, The following question arises:
It seems ovn does not have access to the ovs libraries.
