I'm afraid your question is pretty ambiguous. What do you call a KVM-enabled kernel? Do you mean as a KVM host? Or as a guest? The fact that this is Android is pretty much irrelevant as far as KVM is concerned. Enabling a KVM guest requires nothing in particular. You only need the required drivers that match what your VMM is offering as a platform. Any distro kernel will probably run out of the box. Enabling a KVM host is just a matter of selecting CONFIG_KVM in your kernel configuration and installing the kernel. There are however a bunch of requirements for that host kernel to be able to serve as a hypervisor. The firmware has to boot the kernel in the right context (EL2), and most of the Android-based devices are not exactly cooperative on that front. It would certainly help if you could more exactly detail what you are after, as there are no pre-canned answers to your questions. Thanks, M. -- Without deviation from the norm, progress is not possible. _______________________________________________ kvmarm mailing list kvmarm@lists.cs.columbia.edu https://lists.cs.columbia.edu/mailman/listinfo/kvmarm
