[Xen-devel] [PATCH][RFC] Fix help option of xm create

[Masaki Kanno <kanno.masaki@xxxxxxxxxxxxxx>]

Hi,

I found strange behaviors and messages when tested the following 
commands.
 - xm create --help [config file]
 - xm create --help_config [config file]
 - xm help create

<cf.>
# xm create --help
Usage:  create [options] [vars]

Create a domain
(snip)
    addresses for virtual network interfaces.  This must be a unique
    value across the entire cluster.


Error: Cannot open config file "xmdefconfig"

# xm create --help /xen/vm1.conf 
Usage:  create [options] [vars]

Create a domain.
(snip)
    addresses for virtual network interfaces.  This must be a unique
    value across the entire cluster.


Using config file "/xen/vm1.conf".
The following are automically imported:
    import sys
    import os
    import os.path
    from xen.util.ip import *

# xm create --help_config /xen/vm1.conf 
Using config file "/xen/vm1.conf".
The following are automically imported:
    import sys
    import os
    import os.path
    from xen.util.ip import *

# xm help create
Usage:  create [options] [vars]

Create a domain.
(snip)
    addresses for virtual network interfaces.  This must be a unique
    value across the entire cluster.


Error: Cannot open config file "xmdefconfig"


I made this patch not to display these messages. But I'm wondering 
whether my approach is right, and the "/etc/xen/xmdefconfig" should 
be created to solve this problem.

I need any comments about this matter or reason why the help_config 
option's behavior.
