Re: Need to increase the rx and tx buffer size of my interface
...e 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?
tx_queue_size='512' will not work in the guest with direct type interface,
in fact, no matter what you set, it will not work and guest will get the
default '256'.
We only support vhost-user backend to have more than 256. refer to

Re: Need to increase the rx and tx buffer size of my interface
...ts 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 :

Hi Ashish,
IMO, it is yes, no way to increase tx_queue_size for direct type interface

Re: Need to increase the rx and tx buffer size of my interface
Hi Yalan,
In the previous email you mentioned "tx_queue_size='512' will not work in
the guest with direct type interface, in fact, no matter what you set, it
will not work and guest will get the default '256'. "
So if I am using macvtap for my interfaces, then the device type will
always be direct type. Does it mean that there is no wa...

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

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).

[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
