Hi, I tried using simple weights for setting up the sedf scheduler on Xen 3.1 : [root@mve4 ~]# xm dmesg | grep -i sched (XEN) Command line: /xen.gz-2.6.18-53.el5 maxcpus=4 sched=sedf com1=115200,8n1 console=com1,vga (XEN) Using scheduler: Simple EDF Scheduler (sedf) [root@mve4 ~]# xm sched-sedf Domain-0 -w 2 [root@mve4 ~]# xm sched-sedf vm01 -w 2 [root@mve4 ~]# xm sched-sedf vm02 -w 1 [root@mve4 ~]# xm sched-sedf vm03 -w 1 [root@mve4 ~]# xm sched-sedf vm04 -w 1 [root@mve4 ~]# xm sched-sedf vm05 -w 1 [root@mve4 ~]# xm sched-sedf vm06 -w 1 [root@mve4 ~]# xm sched-sedf Name ID Period(ms) Slice(ms) Lat(ms) Extra Weight Domain-0 -1 -0.0 -0.0 -0.0 -1 -1 vm01 -1 -0.0 -0.0 -0.0 -1 -1 vm02 -1 -0.0 -0.0 -0.0 -1 -1 vm03 -1 -0.0 -0.0 -0.0 -1 -1 vm04 -1 -0.0 -0.0 -0.0 -1 -1 vm05 -1 -0.0 -0.0 -0.0 -1 -1 vm06 -1 -0.0 -0.0 -0.0 -1 -1 [root@mve4 ~]# xm sched-sedf vm01 Name ID Period(ms) Slice(ms) Lat(ms) Extra Weight vm01 -1 -0.0 -0.0 -0.0 -1 -1 I see that the output doesnt show me the correct values that I passed. All values are -ve ( 0 or 1 ). Is this the correct way to set these values ? Am I missing something ? I also managed to kill all VMs while playing around with different values of the slice and period. Any ideas on why this is happening ? Thanks, Devdutt. _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel
