Following patches implement transmit MQ in virtio-net. Also
included is the user qemu changes. MQ is disabled by default
unless qemu specifies it.
1. This feature was first implemented with a single vhost.
Testing showed 3-8% performance gain for upto 8 netperf
sessions (and sometimes 16),
Move queue_index from virtio_pci_vq_info to virtqueue. This
allows callback handlers to figure out the queue number for
the vq that needs attention.

Changes for mq vhost.
vhost_net_open is changed to allocate a vhost_net and
return. The remaining initializations are delayed till
SET_OWNER. SET_OWNER is changed so that the argument
is used to figure out how many txqs to use. Unmodified
qemu's will pass NULL, so this is recognized and handled
Implement mq virtio-net driver.
Though struct virtio_net_config changes, it works with old

sets VIRTIO_NET_F_NUMTXQS.

Hi all!

The bug is reported here:

But there it was closed months ago in KVM 0.12.4. Is a patch going to be
