I know and i've already read, but i cannot find, actually I dont know why in my horizon say my hypervisor is QEMU but actually in my nova.conf at "/etc/nova/nova.conf" have following line:

virt_type = kvm

I dont know why!

hi anhdenday, You can modify the config field virt_type as kvm. Actually, hypervisor in horizon used libvirt API interface virConnectGetType(). Get the name of the Hypervisor driver used. This is merely the driver name; for example, both KVM and QEMU guests are serviced by the driver for the qemu:// URI, so a return of "QEMU" does not indicate whether KVM acceleration is present. For more details about the hypervisor, use virConnectGetCapabilities().
