Hi,

By xentrace, I saw there are many offline states in VCPU scheduling, more in 
HVMs than PV kernels. The comments say that offline means the VCPU is not 
runnable but not blocked (like hotplug and pauses by the system administrator 
or for critical sections in the hypervisor).

Can anyone explain it to me what are the circumstances except for hotplug and 
pauses by the system administrator? And what are the critical sections in the 
hypervisor?

Thanks in advance,
Shawn
