Subject: Offline state in scheduling
Date: Mon, 28 Jun 2010 11:59:15 +0800 [thread overview]
Message-ID: <201006281159133905493@gmail.com> (raw)
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
