It's not about the shortage of timeslices. It's about how many 
timeslices the guest will be given.
Read the wiki more carefully and especially the Algorithm section and 
you will find it's more about credits - if you use the default scheduler.
The host machine/hypervisor will assign the CPU time (timeslice) every 
time the guest has credits or other guest is not asking for that CPU.
