1. When do we exactly specify the scheduler to use ? At dom0 boot time (i.e. when the host boots) or when the domU is created with xm ? At boot time. 'sched=bvt/sedf/credit' needs to be passed to Xen in your boot loader (not to the dom0 kernel). 2. Can we change the scheduler when a domU is already running ? No. 3. Can we change the existing scheduler parameters at runtime for domU or dom0 ? Yes. See 'xm sched-sedf', 'xm sched-credit' etc 4. How do we figure out which scheduler is currently being used 'xm dmesg | grep -i sched' Diwaker _______________________________________________ Xen-users mailing list Xen-users@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-users |
