Description dyuan 2012-05-23 05:23:20 UTC

Description of problem:
Intend to destroy a domain named "001", but the domain whose id is "1" was destroyed.

Version-Release number of selected component (if applicable):
libvirt-0.9.10-20.el6

How reproducible:
always

Steps to Reproduce:
1. # virsh list --all
 Id    Name                           State
----------------------------------------------------
 1     xp                              running
 2     001                            running

2. # virsh destroy 001
Domain 001 destroyed

3. # virsh list --all
 Id    Name                           State
----------------------------------------------------
 -      xp                              shut off
 2     001                            running
 
4. # virsh destroy 001
Domain 001 destroyed

5. # virsh list --all
 Id    Name                           State
----------------------------------------------------
 -      xp                              shut off
 -     001                             shut off

Actual results:
I can't specify the "001" is for domain name or domain id,
I didn't want to destroy the "xp" but it's destroyed by default.

Expected results:
Can specify the option for command such as "destroy", "shutdown"

Comment 1 Daniel Berrangé 2012-05-23 10:55:43 UTC

This is a known limitation of virsh, which we can't do anything about. If you have named your guests soley using numeric digits, then you can only use ID numbers or UUID to refer to them unambiguously.

Comment 2 Daniel Berrangé 2012-05-23 10:56:11 UTC

We should document this limitation in the man page if it isn't already present.

Comment 3 Dave Allan 2012-10-01 21:05:49 UTC

commit 13c69cd0b446669dc53417cb5207c51167a9c14f
Author: Dave Allan <dallan>
Date:   Mon Oct 1 14:01:36 2012 -0400

    Add note about numeric domain names to manpage
    
    Clarify that domains with numeric names can only be identified by
    their domain id.

Comment 4 Jiri Denemark 2012-10-08 18:16:06 UTC

The last rebase to libvirt-0.10.2 was completed and all patches need
to be explicitly backported and sent to rhvirt-patches for review.
Please, set bugs to POST only after sending the backported patches.

Comment 7 Dave Allan 2012-11-20 01:43:22 UTC

Guannan, does 13c69cd0b446669dc53417cb5207c51167a9c14f backport cleanly?

Comment 8 Gunannan Ren 2012-11-20 12:26:31 UTC

Patch sent out today
http://post-office.corp.redhat.com/archives/rhvirt-patches/2012-November/msg00204.html

Comment 11 EricLee 2012-11-28 07:38:34 UTC

Verified this bug in libvirt-0.10.2-10.el6:

# man virsh:
....
The basic structure of most virsh usage is:

virsh [OPTION]... <command> <domain> [ARG]...

Where command is one of the commands listed below; domain is the numeric domain id, or the domain name,
or the domain UUID; and ARGS are command specific options. There are a few exceptions to this rule in
the cases where the command in question acts on all domains, the entire machine, or directly on the xen
hypervisor. Those exceptions will be clear for each of those commands. Note: it is permissible to give
numeric names to domains, however, doing so will result in a domain that can only be identified by
domain id. In other words, if a numeric value is supplied it will be interpreted as a domain id, not as
a name.

The virsh program can be used either to run one COMMAND by giving the command and its arguments on the
shell command line, or a COMMAND_STRING which is a single shell argument consisting of multiple COMMAND
....

And can reproduce it with libvirt-0.2-10.9.el6:
# man virsh
...
The basic structure of most virsh usage is:

virsh [OPTION]... <command> <domain> [ARG]...

Where command is one of the commands listed below, domain is the numeric domain id, or the domain name,
or the domain UUID and ARGS are command specific options. There are a few exceptions to this rule in
the cases where the command in question acts on all domains, the entire machine, or directly on the xen
hypervisor. Those exceptions will be clear for each of those commands.

So changing to VERIFIED.
