If you use Qemu, better consult Qemu folks in qemu-devel. Anyway, just for example, timer interrupt in Qemu is actually coming from user space timer trigger (setitimer maybe.... lately it could be coming from HPET too). So, perhaps what you need to do is add another Qemu monitor commands that manually triggers this timer function. Pay attention for the reentrancy issues though.
