谢谢！！！

The kvm-kmod-devel-XX.tar.gz is just the kernel module which really is independent of qemu. This is the part that takes advantage of the cpu hardware acceleration. You can think of it as an 'accelerator'.

The qemu-kvm-devel-XX.tar.gz is the userspace component which represents the guest virtual machine process. Strictly speaking, you can run other userspace applications like qemu 'on top' of the kernel module accelerator, it's just that right now qemu is the project getting all the mindshare.

The kvm-XX.tar.gz is the combination of both of these components ie. both the guest machine process and hardware accelerator. So to answer your question, yes you can just download the kvm-XX.tar.gz and use that.

hope this helps you!

搞明白了，谢谢！！！
