本文讨论了Libvirt中定时器的问题，特别是当定时器被禁用（timeout=-1）时无法随机启动的问题（timeout=0）。文中提到了在glib主循环中的映射问题导致的困扰，并附带了libvirt-glib-event.c文件的代码变更记录。
In libvirt, it's perfectly possible and widely used to have disabled timers (timeout=-1) and fire them up 'randomly' with timeout=0. However, with current mapping into glib mainloop it's not possible and causing troubles.
