I just saw this so not sure if you&#x27;ll actually see this response, but rump kernel doesn&#x27;t imply Xen or such, that is just a common thing people want to do with them.  It just means kernel drivers that can be used outside the kernel.  Anykernel refers to a kernel that can be used that way with minimal differences and without modifying individual drivers.  So rump kernel is &quot;libkernel&quot; and an anykernel is one way to get a rump kernel.<p>There is a FAQ with more information at:
