![]() ![]() In a modern hosting environment, a small amount of steal time is unavoidable, especially with shared cloud hosting. ![]() You won’t see any CPU steal time in those cases however. It is often not the case of not receiving the CPU time you should be getting, in fact in many cases you can often soak up spare CPU cycles beyond your allocated size. One of the resources it shares is CPU Cycles. Your virtual machine (VM) shares resources with other instances on a single host in a virtualized environment. CPU time is allocated between these processes. Processes such as virtual machines, networking operations and storage I/O requests are given CPU time to process jobs. The hypervisor kernel manages all tasks by scheduling the processes to the physical cores of the server. In a cloud environment, the hypervisor is the interface between the physical server and the virtualized environment. How does a Virtual Machine work with regards to CPU time? The definition of CPU Steal Time is “The percentage of time a virtual CPU waits for a real CPU while the hypervisor is servicing another virtual processor.” And people often ask about steal time – what is it, and why is it reported on their virtual machines? In this article we will explain steal time to better understand what it means for your virtual machine. Virtual machines (VMs) report on different types of usage metrics, such as server load, memory usage, and steal time. ![]()
