A Windows virtual machine (VM) viewed through Task Manager shows CPU utilization averaging 95-100%. What does this indicate?

Add Comment

A Windows virtual machine (VM) viewed through Task Manager shows CPU utilization averaging 95-100%. What does this indicate? 






A. The VM has an impending performance problem. The running processes in Windows Task Manager should be checked to determine what applications are consuming CPU resources.
B. The VM is utilizing most of the CPU resources allocated to it. The CPU Ready value should be checked to determine if this is a resource constraint.
C. The VM has CPU affinity set to CPU 0 and is competing with the service console for CPU resources. esxtop should be run to confirm the diagnosis.
D. The VM CPU reservation is not sufficient.
