Can host hooks be used to implement the following policy to avoid "boot 
storm"?

1.count and sort VMs awaiting for boot.
2.If the count is less than or equal to, for example 5, then boot all 
VMs and exit the script.
3.Otherwise, boot and dequeue vm0 to vm4, and minus the count by 5.
4.Sleep some time, and go to step 2.
