[Xen-users] SEDF default parameters.
Hi All,
I changed the scheduler in my xen installation to sedf, from the default credit based scheduler.
When I do an xm sched-sedf I see :
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
Also a separate query for Dom0 returns :
#xm sched-sedf Domain-0 Name ID Period(ms) Slice(ms) Lat(ms) Extra Weight
Domain-0 -1 -0.0 -0.0 -0.0 -1 -1
Arent there some default parameters that the sedf scheduler uses when it is first used ? The credit based one had a default weight of 256 for all VMs. Whats the case with SEDF ?
What would happen if I were to use these settings as is ?
Thanks, Devdutt.
