libvirt users - Nov 2015 - Re: libvirtd doesn't attach Sheepdog storage VDI disk correctly

Hi,

I am trying to use libvirt with sheepdog.
I am using Debian 8 stable with libvirt V1.21.0
I am encountering a Problem which  already has been reported.

================================================================See here: 
http://www.spinics.net/lists/virt-tools/msg08363.html
================================================================
qemu/libvirtd is not setting the path Variable correctly.

Every time I convert an image to sheepdog

============================================qemu-img  convert
/home/user/temp/debian-8.2.0-amd64-CD-1.iso
sheepdog:debian.iso
===========================================
the dump of the image says

============================================virsh # vol-dumpxml --pool herd
debian.iso
<volume type='network'>
  <name>debian.iso</name>
  <key>herd/debian.iso</key>
  <source>
  </source>
  <capacity unit='bytes'>657457152</capacity>
  <allocation unit='bytes'>658505728</allocation>
  <target>
    <path>debian.iso</path>
    <format type='unknown'/>
  </target>
</volume>
=============================================
It should read

==============================================...
 <path>sheepdog:debian.iso</path>
...
==============================================
I ungraded the system to Debain testing now running:


===============================================virsh # version
Compiled against library: libvirt 1.2.21
Using library: libvirt 1.2.21
Using API: QEMU 1.2.21
Running hypervisor: QEMU 2.4.0
===============================================
The Problem ist still existent.

It should have been solved in libvirt 1.2.17

See here: https://libvirt.org/news.html

====================================================....
update sheepdog client] update sheepdog client path (Vasiliy Tolstov),
.....
====================================================
Nevertheless it doesn't work in Debian 8 testing (libvirt 1.2.21).

This commit does not related to you issue. Also how you define the volume ?

Hi,

I tried two different approaches.

1.) Convert an existing Image with qemu-img

===============================================qemu-img convert -t directsync
lubuntu-14.04.3-desktop-i386.iso
sheepdog:lubuntu1404.iso
================================================
results in

===================================================root@orion2:/var/lib/libvirt/xml#
virsh vol-dumpxml --pool herd
lubuntu1404.iso
<volume type='network'>
  <name>lubuntu1404.iso</name>
  <key>herd/lubuntu1404.iso</key>
  <source>
  </source>
  <capacity unit='bytes'>750780416</capacity>
  <allocation unit='bytes'>750780416</allocation>
  <target>
    <path>lubuntu1404.iso</path>
    <format type='unknown'/>
  </target>
</volume>

=====================================================

2.) creating a new volum using an xml-file (myvol.xml)

===================================================<volume>
         <name>myvol</name>
         <key>sheep/myvol</key>
         <source>
         </source>
         <capacity unit='bytes'>53687091200</capacity>
         <allocation unit='bytes'>53687091200</allocation>
         <target>
           <path>sheepdog:myvol</path>
           <format type='unknown'/>
           <permissions>
             <mode>00</mode>
             <owner>0</owner>
             <group>0</group>
           </permissions>
         </target>
       </volume>
====================================================


now creating the volume

=======================================================virsh vol-create herd 
myvol.xml
========================================================
and now you see:

=========================================================root@orion2:/var/lib/libvirt/xml#
virsh vol-dumpxml --pool herd myvol
<volume type='network'>
  <name>myvol</name>
  <key>herd/myvol</key>
  <source>
  </source>
  <capacity unit='bytes'>53687091200</capacity>
  <allocation unit='bytes'>0</allocation>
  <target>
    <path>myvol</path>
    <format type='unknown'/>
    <permissions>
      <mode>00</mode>
      <owner>0</owner>
      <group>0</group>
    </permissions>
  </target>
</volume>

==========================================================

Is it possible to modify the path-variable manually ?
