Can you add support for arrays in the kernelshark API?  With that, it
looks like adding disassembly output to the kvm plugin should be quite
simple.

Sure, I could add a pevent_get_field_array() or something. Could you
tell me the event and give me an example of what you want to do.

plugin_kvm.c:

kvm_emulate_insn_handler()
{
   fetch insn array and len field
   feed into disassembler
   trace_seq_printf() the disassembled instruction
}
