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
