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.
