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?

Not sure. Adding the libvirt-users mailing list.

Thanks, Naor

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?

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.

I appreciate your help, Naor

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

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

...

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

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