Re: [libvirt] Libvirt multi queue support
How odd.
The Kernel is the first thing I upgraded, here's the output of "uname -r":
3.10.9
I searched for IFF_MULTI_QUEUE in /usr/include/linux/if_tun.h and indeed it wasn't
there.
I believe Kernel 3.10 should support the Multi Queue, do I need to recompile it? maybe
change its config file?

Hi Michal
First of all thanks for your reply.
I followed your advice and the guideline you sent and did the following:
<interface type='bridge'>
<mac address='52:54:00:43:6e:3f'/>
<source bridge='clients'/>
<model type='virtio'/>
<driver name='vhost' queues='5'/>
<address type='pci' domain='0x0000' bus='0x00'
slot='0x04' function='0x0'/>
</interface>
virsh version reports the following:
Compiled against library: libvirt 1.1.1 Using library: libvirt 1.1.1
Using API: QEMU 1.1.1 Running hypervisor: QEMU 1.5.2
When I tried starting the machine I received the following:
error: Failed to start domain NaorDev
error: unsupported configuration: Multiqueue devices are not supported
on this system
Could you please tell what am I missing?
Thanks,
Naor
Your kernel does not support MQ yet. You need to update the kernel. The support can be
checked by executing:
grep IFF_MULTI_QUEUE /usr/include/linux/if_tun.h
(so maybe you'll need to update the linux-headers package as well).
Anyway, the MQ support has been introduced to kernel in the 3.8 release (even though the
docs were introduced in 3.9).
