Virtual machine has CPU contention due to multi-vCPU scheduling issues (co-stop) caused by too many vCPUs. Virtual Machine experiences a high co-stop. The co-stop is the amount of time taken when the virtual machine is ready to run but is experiencing delay because of the co-vCPU scheduling contention. High co-stop occurs when too many vCPUs are configured for the virtual machine, and not enough physical CPUs are available to manage the co-vCPU scheduling. Review the symptoms listed and remove the number of vCPUs from the virtual machine as recommended.
