[Xen-devel] Is it valid to permit numeric only DomName ?

["Yoshinori Katase" <y_katase@xxxxxxxxxxxxxxxx>]

Hi,

Now, Domname is permitted numeric only name.
It is permitted even 0 !
Is this a specification ?

# xm list
Name                              ID Mem(MiB) VCPUs State  Time(s)
Domain-0                           0      512     1 r-----   503.1
22                                21       64     1 ------     1.2
21                                22       64     1 -b----     1.0

I typed "xm shutdown 21", when I want to shutdown DomID 21.
But this command shutdowned Domname 21.

# xm shutdown 21
# xm list
Name                              ID Mem(MiB) VCPUs State  Time(s)
Domain-0                           0      512     1 r-----   506.0
22                                21       64     1 -b----     1.2

It seems that the priority is given to Domname.
But Domname "0" is an exception.

# xm list
Name                              ID Mem(MiB) VCPUs State  Time(s)
Domain-0                           0      512     1 r-----   521.8
0                                 23       64     1 -b----     1.0
# xm shutdown 0
Error: Can't specify Domain-0

This is serious, when many domains are running.
To avoid confusion, Domname shuld be an identifier.
That is the first letter of Domname shuld be alphabetic.
Am I wrong ?
