Hi Yalan and Michal,
Thank you for your response. So what I understand is that I can change
rx_queue size even if I use direct type interface and qemu driver as long
as the driver is virtio. Am I right?
Yes.
If that is the case why am I getting
the error saying that
error: XML document failed to validate against schema: Unable to validate
doc against /usr/share/libvirt/schemas/domain.rng
Extra element devices in interleave
Element domain failed to validate content
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).
for the following xml config? Btw I changed vepa to bridged mode hoping it
would help me. Also note that I tried the following without any driver name
and it still failed.
<interface type='direct'>
<mac address='52:54:00:72:f9:eb'/>
<source dev='enp7s0f0' mode='bridge'/>
<model type='virtio'/>
<driver name='qemu' queues='5' rx_queue_size='512'>
<host csum='off' gso='off' tso4='off'
tso6='off' ecn='off'
ufo='off' mrg_rxbuf='off'/>
<guest csum='off' tso4='off' tso6='off'
ecn='off' ufo='off'/>
</driver>
This works for me. I'm running recent git.
