           Summary: xm sched-sedf silently ignores bad arguments
           Product: Xen
           Version: 3.0.2
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: minor
          Priority: P3
         Component: Tools
        AssignedTo: xen-bugs@xxxxxxxxxxxxxxxxxxx
        ReportedBy: robert.johnston@xxxxxxx


If you pass a bad argument to the sched-sedf subcommand then it is silently
ignored and xm(1) exits with status 0.   This makes it difficult to test or
write tools that wrap xm becuase there is no feedback that indicates that it
received bad input.  It would be better if it printed an appropriate error
message to STDERR and exited with a non-zero status.

This issue waas observed on a Linux dom0 running 3.0.2-2 and a Solaris dom0
running 3.0.2-3 (see output below)

# xm sched-sedf efi-z2 -p -1 -s 5
# echo $?
0
# uname -s -r
SunOS 5.11

[root@thermostat ~]# xm sched-sedf 3 -p -1 -s 5
[root@thermostat ~]# echo $?
0
[root@thermostat ~]# uname -s -r
Linux 2.6.16-xen
