[Bug 1547463] Re: openvswitch-dpdk starting with DPDK_OPTS parameter
This issue happens since DPDK_OPTS parameter is not forwarded to ovs- ctl. To make it working, /etc/init/openvswitch-switch.conf should be modified like the following so that DPDK_OPTS parameter can be forwarded to ovs-ctl if test X"$FORCE_COREFILES" != X; then set "$@" --force-corefiles="$FORCE_COREFILES" fi set "$@" $OVS_CTL_OPTS # To enable openvswitch-dpdk if test X"$DPDK_OPTS" != X; then set "$@" --dpdk-opts="$DPDK_OPTS" fi This patch works fine on my machine. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1547463 Title: openvswitch-dpdk starting with DPDK_OPTS parameter To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/openvswitch-dpdk/+bug/1547463/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1547463] [NEW] openvswitch-dpdk starting with DPDK_OPTS parameter
Public bug reported: To start OpenvSwitch in DPDK mode, Users can use parameter DPDK_OPTS in /etc/default/openvswitch-switch. However, OpenvSwitch-dpdk doesn't start although DPDK_OPTS parameter is uncomment. For example, # DPDK options - see /usr/share/doc/openvswitch-common/INSTALL.DPDK.md.gz DPDK_OPTS='--dpdk -c 0x1 -n 4' What I did was, #install openvswitch-dpdk package $sudo apt-get install openvswitch-switch-dpdk #enable hugepage on /etc/default/grub GRUB_CMDLINE_LINUX="transparent_hugepage=never hugepagesz=1G hugepages=4 default_hugepagesz=1G" $sudo update-grub $sudo reboot #mount hugepage $sudo mount -t hugetlbfs -o pagesize=1G none /dev/hugepages # DPDK setup $sudo modprobe uio_pci_generic $sudo dpdk_nic_bind --bind=uio_pci_generic p1p1 #uncomment DPDK_OPTS on /etc/default/openvswitch-switch DPDK_OPTS='--dpdk -c 0x1 -n 4' # update alternatives ovs-vswitchd and start openvswitch $sudo update-alternatives --set ovs-vswitchd /usr/lib/openvswitch-switch-dpdk/ovs-vswitchd-dpdk $sudo start openvswitch-switch # check if openvswitch-dpdk enabled ps -ef doesn't show ovs-vswitchd process running with --dpdk option. Also, /var/log/openvswitch/ovs-ctl.log doesn't show any DPDK relevant message.
