I wish to debug it through fast models. My problem is that FVP uses 3.4 kernel, and 3.9 from "git:// git.kernel.org/pub/scm/virt/kvm/kvm.git " does not boot it. Do you have a ready kernel for FVP ?

Mainline kernels should boot just fine on Arm fast models. I strongly recommend you use a much newer kernel version for anything KVM-related. -Christoffer ^ permalink raw reply [flat|nested] 4+ messages in thread

You're probably not getting timer interrupts, which could be because of a number of things. Your bootloader in the .axf image could be the wrong wrong or configured incorrectly, the DT could be the wong one for the model, or your configuration parameters could otherwise be incorrect. This is a basic "bring up Linux on the fast model" question, and doesn't really belong on the KVM/ARM list. Also note, that if you do want to play with KVM on an Arm system, then Cortex-A9 does not have the virtualization extensions.
