Build Update for david-marchand/ovs
-------------------------------------

Build: #12
Status: Errored

Duration: 1 hr, 8 mins, and 17 secs
Commit: a4c1ac9 (vhost_fixes)
Author: David Marchand
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 ($6 == "enabled") {
      en++;
    }
  }
  END {
    print "total: " tot ", enabled: " en
  }'
  sleep 1
done

total: 66, enabled: 66
total: 6, enabled: 2

Note: this patch requires a fix for the vhost library submitted here:
http://patchwork.dpdk.org/patch/52680/

Without it, this change will do nothing but have openvswitch complain
that the vhost device is unknown:

dpdk|INFO|VHOST_CONFIG: vhost peer closed
dpdk|ERR|VHOST_CONFIG: (0) device not found.

dpdk|INFO|VHOST_CONFIG: vhost peer closed
dpdk|ERR|VHOST_CONFIG: (1) device not found.
