Description Edgar Hoch 2010-08-19 17:49:41 EDT
Description of problem:

When I use "virsh pool-create XMLFILE" where XMLFILE is a file previously created by "virsh pool-dumpxml poolname" and pool "poolname" does not exist (for example, after reinstallation of fedora), then this command does not create /etc/libvirt/storage/poolname.xml .
A later command like "virsh pool-autostart poolname" shows an error:
"internal error pool has no config file".

When I use "virsh pool-define XMLFILE" then the config file is created.

In the man page "virsh pool-create XMLFILE" should do the same as "virsh pool-define XMLFILE" followed by a "virsh pool-start poolname".

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. Create a libvirt storage pool if none exists, for example by virt-manager.
2. Create an xml description of the storage pool using
   virsh pool-dumpxml poolname > XMLFILE
3. Remove the storage pool from the management of libvirt:
   virsh pool-destroy poolname
   Or use a new installed fedora system.
4. Recreate the storage pool:
   virsh pool-create XMLFILE

Actual results:
/etc/libvirt/storage and /etc/libvirt/storage/poolname.xml are not created.

Expected results:
/etc/libvirt/storage and /etc/libvirt/storage/poolname.xml should exist.
Comment 1 Edgar Hoch 2010-08-20 14:29:48 EDT
The commands "virsh create XMLFILE" versus "virsh define XLMFILE" followed by "virsh start DOMAIN" have the same error as above for pools:
The first does not create the file /etc/libvirt/qemu/DOMAIN.xml, the second does.

I think, both should do the same.
Comment 2 Bug Zapper 2011-06-01 07:05:28 EDT
This message is a reminder that Fedora 13 is nearing its end of life.
Approximately 30 (thirty) days from now Fedora will stop maintaining
and issuing updates for Fedora 13.  It is Fedora's policy to close all
bug reports from releases that are no longer maintained.  At that time
this bug will be closed as WONTFIX if it remains open with a Fedora 
'version' of '13'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version' 
to a later Fedora version prior to Fedora 13's end of life.

Bug Reporter: Thank you for reporting this issue and we are sorry that 
we may not be able to fix it before Fedora 13 is end of life.  If you 
would still like to see this bug fixed and are able to reproduce it 
against a later version of Fedora please change the 'version' of this 
bug to the applicable version.  If you are unable to change the version, 
please add a comment here and someone will do it for you.

Although we aim to fix as many bugs as possible during every release's 
lifetime, sometimes those efforts are overtaken by events.  Often a 
more recent Fedora release includes newer upstream software that fixes 
bugs or makes them obsolete.

The process we are following is described here: 
Comment 3 Cole Robinson 2011-06-10 13:48:23 EDT
This is intentional behavior. all 'create' operations make transient objects, meaning when they are shut down libvirt forgets about them. part of this behavior is that no persistent XML config is written to disk.
