I'm trying to clone a volume in a storage pool and I'm following the steps
described here:
http://libvirt.org/docs/libvirt-appdev-guide-python/en-US/html/libvirt_ap...
My code looks like:
destXML = """
<volume>
<name>"""+newDiskName+""".qcow2</name>
<target>
<path>/jffs2/disk0/"""+poolName+'/'+newDiskName+""".qcow2</path>
<format type='qcow2'/>
<permissions>
<owner>-1</owner>
<group>-1</group>
<mode>0644</mode>
<label>virt_image_t</label>
</permissions>
</target>
</volume>"""
srcDisk = tmpPool.storageVolLookupByName(vDisk)
newVol = sp.createXMLFrom(destXML,srcDisk, 0)
According to the steps described in the link, this should be it; but I
can't start any VM that are using this volume.
Also comparing the volume XML files for src/dest it looks like the format
is not copied over:
source:
<volume type='file'>
<name>k.qcow2</name>
<key>/jffs2/disk0/sp/vDisk.qcow2</key>
<source>
</source>
<capacity unit='bytes'>3221225472</capacity>
<allocation unit='bytes'>332075008</allocation>
<target>
<path>/jffs2/disk0/sp/vDisk.qcow2</path>
*<format type='qcow2'/>*
<permissions>
<mode>0644</mode>
<owner>0</owner>
<group>0</group>
</permissions>
<timestamps>
<atime>1455879195</atime>
<mtime>1455879171</mtime>
<ctime>1455879171</ctime>
</timestamps>
</target>
dest:
<volume type='file'>
<name>newDiskName.qcow2</name>
<key>/jffs2/disk0/sp/newDiskName.qcow2</key>
<source>
</source>
<capacity unit='bytes'>3221225472</capacity>
<allocation unit='bytes'>326868992</allocation>
<target>
<path>/jffs2/disk0/sp/newDiskName.qcow2</path>
*<format type='raw'/>*
<permissions>
<mode>0644</mode>
<owner>0</owner>
<group>0</group>
</permissions>
<timestamps>
<atime>1455878686</atime>
<mtime>1455878681</mtime>
<ctime>1455878681</ctime>
</timestamps>
</target>
</volume>
I this a bug in libvirt->createXMLFrom ?? Or am I missing something?
Thanks,
Andrei
