[Xen-devel] [PATCH] Fix sched commands for when wrong domain is given

[Masaki Kanno <kanno.masaki@xxxxxxxxxxxxxx>]

Hi,

I found strange issues. I gave a wrong domain name to the xm sched 
commands. The xm sched commands only showed the header at that time. 
And the xm sched-sedf command did not become an error when I tried 
to set scheduler parameters. 

# xm sched-credit -d Nonexistent-domain
Name                              ID Weight Cap 

# xm sched-sedf Nonexistent-domain
Name                              ID Period(ms) Slice(ms) Lat(ms) Extra Weight
# xm sched-sedf Nonexistent-domain -w 10
# 


I fixed it. When the wrong domain name is given, the xm sched 
commands show the following error messages. 

# xm sched-credit -d Nonexistent-domain
Error: Domain 'Nonexistent-domain' does not exist.
Usage: xm sched-credit [-d <Domain> [-w[=WEIGHT]|-c[=CAP]]]

Get/set credit scheduler parameters.
  -d DOMAIN, --domain=DOMAIN     Domain to modify 
  -w WEIGHT, --weight=WEIGHT     Weight (int) 
  -c CAP, --cap=CAP              Cap (int) 

# xm sched-sedf Nonexistent-domain
Error: Domain 'Nonexistent-domain' does not exist.
Usage: xm sched-sedf <Domain> [options]

Get/set EDF parameters.
  -p [MS], --period[=MS]         Relative deadline(ms) 
  -s [MS], --slice[=MS]          Worst-case execution time(ms). (slice < 
                                 period)
  -l [MS], --latency[=MS]        Scaled period (ms) when domain performs 
                                 heavy I/O
  -e [FLAG], --extra[=FLAG]      Flag (0 or 1) controls if domain can run 
                                 in extra time.
  -w [FLOAT], --weight[=FLOAT]   CPU Period/slice (do not set with 
                                 --period/--slice)

# xm sched-sedf Nonexistent-domain -w 10
Error: Domain 'Nonexistent-domain' does not exist.
Usage: xm sched-sedf <Domain> [options]

Get/set EDF parameters.
  -p [MS], --period[=MS]         Relative deadline(ms) 
  -s [MS], --slice[=MS]          Worst-case execution time(ms). (slice < 
                                 period)
  -l [MS], --latency[=MS]        Scaled period (ms) when domain performs 
                                 heavy I/O
  -e [FLAG], --extra[=FLAG]      Flag (0 or 1) controls if domain can run 
                                 in extra time.
  -w [FLOAT], --weight[=FLOAT]   CPU Period/slice (do not set with 
                                 --period/--slice)
