Hi, I am trying to understand the concept of cpu steal time. I have a few questions about it. According to the link https://scoutapm.com/blog/understanding-cpu-steal-time-when-should-you-be-worried , it is defined as follows: "Steal time is the percentage of time a virtual CPU waits for a real CPU while the hypervisor is servicing another virtual processor." I have two questions regarding that. 1. What do we mean by "percentage of time" ? Which time is it alluding to ? Is it the "cpu time" allocated by the scheduler to that kvm process ? Or, is it the general waiting time that vcpu process has to wait in the run queue before getting the cpu for execution ? If this is true, then it is normal for that vcpu process like any other process on the system to wait in the runqueue. Then what is this fuss about ? 2. How can we read this steal time ? Can we see it from within the vm and from the hypervisor host also ? If so, how ? Does this mean that we cant see the "st" field if we execute the top command on a server without any hypervisor ? Please explain. Thanks Kumar
