[libvirt-users] how to make the volume's format to qcow2 when creating volume
hi,all
the following are files of pool and volume.
storage pool is based on logical(LVM) and iscsi,now I create volume
specified the format to "qcow2"
*pool.xml*
<pool type='logical'>
<name>pool_190</name>
<source>
<device
path='/dev/disk/by-path/ip-192.168.0.190:3260-iscsi-iqn.2012-11.com.cloudking:server.target1-lun-1'/>
</source>
<target>
<path>/dev/pool_190</path>
</target>
</pool>
*volume.xml*
<?xml version="1.0" encoding="UTF-8" ?>
<volume>
<name>volume1</name>
<capacity unit="GB">1</capacity>
<target>
<format type="qcow2" />
</target>
</volume>
*the problmes is :when the volume created successfully,However, the
volume's format is 'raw'*
like this
image: /dev/pool_190/volume1
*file format: raw*
virtual size: 1.0G (1073741824 bytes)
disk size: 0
how to resolve this troublesome.
libvirt :0.9.8
os:ubuntu12.04
many thanks for any reply....

You're using LVM, so its always creating it raw.
