xen

Hi everyone,

This is my question. I have one Xen server with 8 CPU's and 6 virtual machine running, each virtual hard disk are running in diferent physical hardisk. Everything worked fine but sometimes one virtual machine get almost whole CPU, if the Domain-0 is 90% that is normal, the virtual machine is 500% usage of CPU. I have improved that it is not depends who are working with the VM even when nobody are working with the server this still happens. I dont know what happen. Anyone have any idea?¿ or anyone have happened the same?¿

disparity between `top`'s given CPU % and process CPU usage total
