KVM guest is on top of QEMU, and KVM is used by QEMU to
provide hardware-accelerated virtualization.
Although there is an association between them,
difference is very obvious.
The function named is_kvm() is only can be applied to
determine QEMU, which couldn't distinguish QEMU and QEMU-KVM.
In other words,
Its' name doesn't match its' content and function.
so is_qemu() more reasonable.
