Log Message:
-----------
netdev-dpdk: Reset queue number for vhost devices on vm shutdown.
Rather than poll all disabled queues and waste some memory for vms that
have been shutdown, we can reconfigure when receiving a destroy
connection notification from the vhost library.
$ while true; do
ovs-appctl dpif-netdev/pmd-rxq-show |awk '
/port: / {
tot++;
if ($5 == "(enabled)") {
en++;
}
}
END {
print "total: " tot ", enabled: " en
}'
sleep 1
done
total: 66, enabled: 66
total: 6, enabled: 2
This change requires a fix in the DPDK vhost library, so bump the minimal
required version to 18.11.2.
