Hello experts,

I am trying to use the multi queue support on a Linux guest running Kernel 3.9.7.

The host's virsh version command reports the following output: 
Compiled against library: libvirt 0.10.2
Using library: libvirt 0.10.2
Using API: QEMU 0.10.2
Running hypervisor: QEMU 0.12.1

The problem is that virtio_has_feature(vdev, VIRTIO_NET_F_MQ) returns FALSE and I don't know why.

I'll really appreciate your help.

Thanks,
Naor

Is it RHEL or CentOS or Scientific Linux, or something else?  If
RHEL/CentOS, what release?

This version of QEMU is too old.  It's possible that 6.5 will have
multiqueue, but I'm not entirely sure.

Hi Paolo,

The host is running CentOS release 6.3 (Final).
I did "yum upgrade libvirt" and "yum upgrade qemu-kvm" a couple of days ago and ended up with these versions.

What do you suggest regarding qemu? compile 6.5 or later myself?

I appreciate your help,
Naor

RHEL/CentOS 6.5 is not yet out, it's still a few months before it's
released.

You can compile QEMU 1.6 from source, or wait for CentOS to have the
feature.

Hi Paolo and thanks for your help.

I upgraded the following (compiled from source)
qemu : 1.5.2 stable
libvirt : 1.1.1

but for some reason when I run the version command inside virsh:

Compiled against library: libvirt 1.1.1
Using library: libvirt 1.1.1
Using API: QEMU 1.1.1
Running hypervisor: QEMU 0.12.1

It says that my running Hypervisor is QEMU 0.12.1

Could you please tell me what did I miss, how do I upgrade the hypervisor?

Thanks,
Naor

Not sure.  Adding the libvirt-users mailing list.
