[Qemu-devel] using virtio-net multiqueues

[William Dauchy]

Hello,

Using qemu2.1 I'm starting a vm with this network interface:

[netdev "vifA.0"]
  type = "tap"
  vhost = "on"
  ifname = "vifA.0"
  downscript = "no"
  script = "no"
  queues = "2"

[device "vifA.0"]
  driver = "virtio-net-pci"
  netdev = "vifA.0"
  mac = "00:16:3e:1a:4e:11"
  mq = "on"
  vectors = "5"

during qemu startup I see several queues in
/sys/devices/virtual/net/vifA.0/queues and it quickly disappears; at
the end I see only one rx and one tx.
Am I wrong on something? What can I do to help debug this situation?

Best regards,
