On an ESXi server hosting several Windows VMs I see that the average CPU usage is usually less than 60%, that sounds normal.
Many VM are powered on but about idle, while few other are largely used to test appluication and operating system setup procedures.
The CPU Ready counter for working VMs can rise to 2000, that sounds strange as the average CPU usage for the whole of the server is usually less than 60%.
Can anybody please help me understanding the reason of this strange (to me) behavior?
Can anybody please help me detecting the configuration errors and, maybe, eliminate them?
How many vCPUs are in these guests?
How many VMs are you running on the host? Do they have more than 1 vCPU? What type and how many processors do your ESX hosts have?
This information will help determine what could be causing this behavior -
