[Pkg-libvirt-maintainers] Bug#709081: libvirt-bin: virsh doesn't allow to define LVM pool with custom name.

[Алексей Ступников]

I tried to add a LVM pool in virsh shell.
I used the following command to create the pool: pool-define-as 
POOL_NAME logical --target /dev/VG
When I tried to start it with a command 'pool-start POOL_NAME, I get the 
following error:
"error: Failed to start pool POOL_NAME
error: internal error Child process (/sbin/vgchange -aly POOL_NAME) 
status unexpected: exit status 5"

Output of pool-dumpxml POOL_NAME:
<pool type='logical'>
<name>POOL_NAME</name>
<uuid>32087a2e-e930-0add-024a-cce49dec1cd4</uuid>
<capacity unit='bytes'>0</capacity>
<allocation unit='bytes'>0</allocation>
<available unit='bytes'>0</available>
<source>
<name>POOL_NAME</name>
<format type='unknown'/>
</source>
<target>
<path>/dev/VG</path>
<permissions>
<mode>0700</mode>
<owner>4294967295</owner>
<group>4294967295</group>
</permissions>
</target>
</pool>
