Thanks for making these two works.
I think it would be great if we could, in this case, output somehow and
somewhere that we are actually showing some defaults, instead than
anything that is really in use.
I don't know whether with something like this:
# xl sched-rtds
Cpupool Pool-0: sched=RTDS
Name ID Period Budget
Domain-0 (defaults) 0 10000 4000
vm1 (defaults) 1 10000 4000
vm2 (defaults) 2 10000 4000
# xl sched-rtds -d vm1
Name ID Period Budget
vm1 (defaults) 1 10000 4000
Or by "just" adding a note before the actual output:
# xl sched-rtds -d vm1
Showing per-vm(s) default scheduling parameters,
use `-v' for seeing the actual parameters of each vcpu
Name ID Period Budget
vm1 1 10000 4000
The latter is more verbose, but I think is what I see as more useful
(and, probably, the easier to implement).
Regards,
Dario
