Yesterday redhat released version 0.10.6 of qemu-kvm, the userspace component running “on top” of the linux virtual machine software. These releases don’t include the kvm kernel modules so you’ll have to use kernel modules provided by your linux software distribution or compile your own from the kvm-kmod stable branch releases.
