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.
