Have you tried to change pmd-cpu-mask? Because that is mask of bits
representing the CPUs you allow PMDs to be created. In this case,
you are saying '0x6' (binary mask: 0110), so only two CPUs.
Also check ovs-vswitchd.conf.db(5) man-page:
other_config : pmd-cpu-mask: optional string
Specifies CPU mask for setting the cpu affinity of PMD (Poll
Mode
Driver) threads. Value should be in the form of hex string,
similar
to the dpdk EAL ’-c COREMASK’ option input or the ’taskset’
mask
input.
The lowest order bit corresponds to the first CPU core. A set
bit
means the corresponding core is available and a pmd thread will
be
created and pinned to it. If the input does not cover all
cores,
those uncovered cores are considered not set.
If not specified, one pmd thread will be created for each numa
node
and pinned to any available core on the numa node by default.
