Run omething like "iostat -mx 3" on the virtual server. If disk utilization is often close to 100%, then you have the culprit. Sometimes you don't necessarily need to have a dedicated disk. You have to make sure that it's used optimally. e.g: - whenever possible, don't use HVM guest. Use PV guests instead. - use block device (partition, LVM, whole disk) instead of file-backed image - when you have to use file-backed image, use tap:aio instead of file:/ -- Fajar _______________________________________________ Xen-users mailing list Xen-users@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-users |
