Re: [libvirt-users] Multi Queue KVM Support

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?

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.
