[virt-tools-list] Virt-manager doesn't attach Sheepdog storage VDI disk correctly

[Dmitriy Slachshyov]

Hi,

Recently, I 've installed libvirt (version 1.2.17) and sucessfully
attached working sheepdog storage (version 0.9.2) as a pool.
I use virt-manager 1.2.1 

Everything looks fine. I can create and remove VDI disks in the storage
pool without any errors.

Everytime, when I try to connect my created VDI disk using virt-manager
to any virtual machine, I see that my attached disk is not a disk from
sheepdog storage. While connecting VDI storage disk, the disk creates
on the local file system (newly created storage with full path
$HOME/test).

So, I can't attach real VDI disk from sheepdog storage to my virtual
machine.

As I see, this problem appears because the sheepdog's target path is
NULL and/or xml-parsing isn't valid for sheepdog.

The commands at bottom of message may help you!

# virsh pool-list
 Name                 State      Autostart 
-------------------------------------------
 default              active     yes       
 $MYUSER              active     yes       # suddenly created storage
pool while connecting sheeddog's VDI disk to.
 LVM                  active     yes       
 sheepdog             active     yes       

# virsh pool-dumpxml sheepdog
<pool type='sheepdog'>
  <name>sheepdog</name>
  <uuid>7333590b-1dcc-46e2-9af6-09c9c96af70a</uuid>
  <capacity unit='bytes'>19414155264</capacity>

    <name>sheepdog</name>
  </source>
</pool>

# virsh vol-list sheepdog
 Name                 Path                                    
--------------------------------------------
 test                 test                                    

# dog vdi list -a 192.168.100.10
 Name  Id  Size    Used    Shared    Creation time      VDI id

 test  0   8.0 GB  0.0 MB  0.0 MB    2015-08-02 00:09   7c2b25    2:2


Also look at the next issue:

- <disk type='file' device='disk'>             # It's automatically
created by virt-manager
+ <disk type='network'>                        # I made it manually and
it works
    <driver name='qemu' type='raw'/>
-   <source file='$HOME/test'/>
+   <source protocol="sheepdog" name="test"/>
    <target dev='hda' bus='ide'/>
    <address type='drive' controller='0' bus='0' target='0' unit='0'/>
  </disk>
