[Xen-devel] [PATCH] Show usage message of xm migrate

[Masaki Kanno <kanno.masaki@xxxxxxxxxxxxxx>]

Hi,

I think that error messages of xm migrate command are unkind.

# xm migrate
Error: Invalid arguments: []
# xm migrate vm1 192.168.0.10 XXX
Error: Invalid arguments: ['vm1', '192.168.0.10', 'XXX']

If invalid arguments are specified, this patch shows an usage 
message.

# xm migrate
