I like perf. Really. But I still don't see why it wouldn't be able to live in its own tree either.

Having the split between KVM and user space is necessary. One lives in kernel space, the other one in user space. The split between qemu and virt-manager is something I don't like either. But then again I don't like virt-manager :). But what does this have to do with pulling something into the kernel? And reimplementing something that's already been there?
