ESXI 4.1 Host draws HIGH CPU at Idle
Posted on 2011-09-16
Hello Expert Friends,
I manage a single ESXI host for a client and lately, (but maybe I did not notice it before) it is showing 50% CPU in the VI client when the system is totally idling. It is a IBM-Lenovo RD120 (M6447-18U) server running 12 VM's as Virtual Desktops. When a user logs in, performance is very poor and simply opening a browser window usually pegs CPU for a 30 seconds or more. Given is shows 50% usage totally idling (and all the VM's show nearly 0 CPU usage) makes me think there is a serious issue. Why would the CPU be so high when it is not taken by the VM's? All health parameters in the VI client logs are good.
