-----------------------
This package provides a DPDK enabled version of the OpenvSwitch vswitchd
binary; by default, the ovs-vswitchd binary from openvswitch-switch will
be used:
$ update-alternatives --query ovs-vswitchd
Name: ovs-vswitchd
Link: /usr/sbin/ovs-vswitchd
Status: auto
Best: /usr/lib/openvswitch-switch/ovs-vswitchd
Value: /usr/lib/openvswitch-switch/ovs-vswitchd
Alternative: /usr/lib/openvswitch-switch-dpdk/ovs-vswitchd-dpdk
Priority: 50
Alternative: /usr/lib/openvswitch-switch/ovs-vswitchd
Priority: 100
DPDK provides fast packet processing in userspace, and has some specific
requirements in terms of system configuration - see the upstream
documentation for more details:
/usr/share/doc/openvswitch-common/INSTALL.DPDK.md.gz
DPDK has a minimum CPU feature set of SSE3, so is not appropriate for all
amd64 CPU types hence is not enabled by default.
To switch to the DPDK version:
sudo update-alternatives --set ovs-vswitchd \
/usr/lib/openvswitch-switch-dpdk/ovs-vswitchd-dpdk
sudo service openvswitch-switch restart
and to switch back:
sudo update-alternatives --set ovs-vswitchd \
/usr/lib/openvswitch-switch/ovs-vswitchd
sudo service openvswitch-switch restart
