Description of problem: The network init-scripts (including ifcfg files in /etc/sysconfig/network-scripts) are deprecated in favor of NetworkManager. In order to migrate away from init-scripts in os-net-config, we need to support a NetworkManager implementation in addition to the ifcfg implementation. Version-Release number of selected component (if applicable): OpenStack Stein Actual results: Currently all interface configuration is done in ifcfg files, and additionally there is a script to configure SR-IOV virtual functions at boot time. os-net-config also has support for ethtool commands and ovs-vsctl commands for OVS. Expected results: In order to switch to a NetworkManager implementation, we will use an interface to NetworkManager such as nmcli, nmstate, or Ansible Networking. Additionally, NetworkManager will have to have feature parity for interface types supported by os-net-config. Additional info: Most of the interface types are supported in NetworkManager, but we should confirm support in NetworkManager for the following device types: OVS bonds OVS patches (internal patches between bridges) OVS tunnel ports OVS User bridge (DPDK bridge) OVS DPDK ports OVS DPDK bonds Infiniband network interfaces VPP interfaces VPP bonds Contrail vRouter Contrail vRouter DPDK Big Switch IVS bridges Big Switch NFVSwitch bridges (DPDK) Big Switch NFVSwitch ports (DPDK) Big Switch NFVSwitch internal patches (DPDK) In addition, SR-IOV VF virtual functions are recently supported in NetworkManager, but we should confirm wheter the os-net-config SR-IOV configuration script that gets run by systemd is required when using NetworkManager to manage SR-IOV VFs.
It appears that OVS bond support was added at the same time OVS bridge support was added: https://bugzilla.redhat.com/show_bug.cgi?id=1555015 Support for ethtool options is being added: https://bugzilla.redhat.com/show_bug.cgi?id=1335409 https://bugzilla.redhat.com/show_bug.cgi?id=1614700 Support for OVS DPDK ports in progress: https://bugzilla.redhat.com/show_bug.cgi?id=1612503 Infiniband interfaces and bonds are currently supported: https://bugzilla.redhat.com/show_bug.cgi?id=1339008

Created RFE for supporting VPP interfaces and bonds in NetworkManager: https://bugzilla.redhat.com/show_bug.cgi?id=1645717 Note that VPP config doesn't use ifcfg files, but instead uses /var/lib/os-net-config/dpdk_mapping.yaml and /etc/vpp/vpp-exec files to configure VPP interfaces. Because of that, it isn't clear if NetworkManager needs to support VPP directly, or if os-net-config can continue to write DPDK/VPP configuration to these files when we implement NetworkManager support.
(In reply to Dan Sneddon from comment #3) > Created RFE for supporting VPP interfaces and bonds in NetworkManager: > https://bugzilla.redhat.com/show_bug.cgi?id=1645717 While VPP is supported in os-net-config, we have never supported VPP in OpenStack Platform. For that reason, I think VPP support in NetworkManager is not a priority for OpenStack at this time.
network-scripts has been included for os-net-config here - https://review.rdoproject.org/r/#/c/17626/.
Additional ethtool options are required for NetworkManager support for OpenStack Platform. Specifically -C and -G are required to set coalesce and ring settings.

This will need to go through the exception TRAC process to be be included in 17.1
Hi Karthik, I have created these bugs to track the dedicate features: * Bug 2222284 - [RFE] Support third party interface * Bug 2222289 - [RFE] Support OVS SR-IOV TC Hardware Offload We will provide demo for both feature for you to try out.
