[AMD Official Use Only - General] Hi Sindhu,
You can try enabling the dpdk logging with: ovs-appctl vlog/set file:dpdk:dbg DPDK logs should be in ovs-vswitchd log itself as indicated below. 2024-02-29T11:02:54.327Z|00115|dpif_netdev|INFO|Core 10 on numa node 0 assigned port 'dpdk0' rx queue 0 (measured processing cycles 0). 2024-02-29T11:02:54.332Z|00116|dpif|WARN|netdev@ovs-netdev: port_set_config failed (Invalid argument) 2024-02-29T11:02:54.332Z|00117|ofproto|WARN|br0: datapath configuration on port 1 (dpdk0) failed (Invalid argument) 2024-02-29T11:02:54.335Z|00118|dpdk|INFO|Device with port_id=1 already stopped 2024-02-29T11:02:54.350Z|00119|dpdk|INFO|ice_set_rx_function(): Using AVX2 OFFLOAD Vector Rx (port 1). 2024-02-29T11:02:54.813Z|00120|netdev_dpdk|INFO|Port 1: 6c:fe:54:6b:4f:11 2024-02-29T11:02:54.814Z|00121|netdev_dpdk|INFO|dpdk1: rx-steering: default rss 2024-02-29T11:02:54.814Z|00122|dpif_netdev|INFO|Performing pmd to rx queue assignment using cycles algorithm.

I'm facing some issues while bringing up a dpdk interface on ovs-dpdk on debian-12. Dpdk version is 22.11.1. Dpdk seems to fail to allocate a mempool, even though there seem to be enough free huge page memory available on the machine. I tried to enable dpdk debugs using the following command, ovs-vsctl set Open_vSwitch . other_config:dpdk-extra="--log-level=lib.mbuf:debug" The command was accepted, but I don't see any logs from dpdk anywhere in my /var/log. I get the following information from ovs logs. Feb 22 01:03:42 cep ovs-vswitchd[108468]: ovs|00237|netdev_dpdk|ERR|Failed to create mempool "ovs013337e900021580020512" with a request of 20512 mbufs Feb 22 01:03:42 cep ovs-vswitchd[108468]: ovs|00238|netdev_dpdk|ERR|Failed to create memory pool for netdev vhost-user0, with MTU 1500 on socket 0: No such file or directory Feb 22 01:03:42 cep ovs-vswitchd[108468]: ovs|00239|dpif_netdev|ERR|Failed to set interface vhost-user0 new configuration Checked ovs code, and its callingvrte_pktmbuf_pool_create(), which is failing with "No such file or directory". I would like to enable debugs for lib.mbuf. Please let me know if I'm missing anything. Thanks, Sindhu
