Re: Need to increase the rx and tx buffer size of my interface
Hi Ashish,
I have tested with your xml in the first mail, and it works for
rx_queue_size(see
below).
multiqueue need to work with vhost backend driver. And when you set
"queues=1" it will ignored.
Please check your qemu-kvm-rhev package, should be newer than
qemu-kvm-rhev-2.9.0-16.el7_4.2
And the logs?

This suggests why I saw 256 again after restarting.
So now I tried again to edit the xml via virsh edit command and used the
following to set the parameters.
<driver name='qemu' txmode='iothread' ioeventfd='on' event_idx='off'
queues='1' rx_queue_size='512' tx_queue_size='512'>
</driver>
It was not accepted and I got the error saying :

What's your libvirt version? For rx_queue_size you need 2.3.0 or newer.
For tx_queue_size you need 3.7.0 or newer (not that there's one yet).

Re: Need to increase the rx and tx buffer size of my interface
Hi Michal,
An update to what I have already said : when I try adding <driver
name='qemu' txmode='iothread' ioeventfd='on' event_idx='off' queues='1'
rx_queue_size='512' tx_queue_size='512'> although it showed me the error as
mentioned, when I checked the xml again I saw that <driver name='qemu'
txmode='iothread' ioeventfd='on' event_idx='off' > is added to the
interface.
The missing parameters are :...

[PATCH v4 0/3] virtio_net: allow hypervisor to indicate linkspeed and duplex setting
We have found it useful to be able to set the linkspeed and duplex
settings from the host-side for virtio_net. This obviates the need
for guest changes and settings for these fields, and does not require
custom ethtool commands for virtio_net.
The ability to set linkspeed and duplex is useful in various cases
as described here:
