Hello
I want to implement in xen hypervisor but I don't know how to do it. I
search in google but I do not found how to use the xen timer (not
linux).
when I compile xen the timer run only once. here is my code.
static void timer_handler(void *unused)
{
printk("hello world in timer\n");
}
static struct timer *domain_timer;
somewhere in my xen source I initialise the timer:
domain_timer = xmalloc(struct timer);
init_timer(domain_timer, timer_handler,NULL,0);
set_timer(domain_timer, SECONDS(60));
please can anybody explain what is wrong in my code
Thank you

I believe Xen timers are one-shot only. If you want a periodic timer
then you will need to rearm it at the end of your handler.
Check the plt_overflow_timer for an example of this sort of thing.
Ian.
