Re: [libvirt] virStoragePoolDefParseString() fails with the following pool xml
I just added target path to pool XML. It doesn't resolve the issue.
virStoragePoolDefParseString() returns NULL.

Hi,
I have the following Pool XML
<pool type='netfs'>
<name>NFS ISO library</name>
<uuid>6142b786-378d-9def-bc96-2d0dc0466c13</uuid>
<capacity>838729728</capacity>
<allocation>838729728</allocation>
<available>148315040</available>
<source>
<host name='telos'/>
<dir path='/images/autoinstall'/>
<format type='auto'/>
</source>
<target>
<permissions>
<mode>00</mode>
<owner>0</owner>
<group>0</group>
</permissions>
</target>
</pool>
I'm passing this string to virStoragePoolDefParseString() to get a
virStoragePoolDefPtr
But it returns NULL. Can anyone explain if there's something wrong with the XML
format?
I ran gdb and I kind of figured out that it fails at
if (virStoragePoolDefParseSource(ctxt, &ret->source, ret->type,
source_node) < 0) in
virStoragePoolDefParseXML()
in ~/src/conf/storage_conf.c
I think you've got the wrong place here. If I feed your XML to 'virsh
pool-define'
using the QEMU driver, then I get
error: XML description for missing storage pool target path is not well formed or invalid
which is from
static virStoragePoolDefPtr
virStoragePoolDefParseXML(xmlXPathContextPtr ctxt) {
....
if ((ret->target.path = virXPathString("string(./target/path)", ctxt)) ==
NULL) {
virStorageReportError(VIR_ERR_XML_ERROR,
"%s", _("missing storage pool target
path"));
goto cleanup;
}
You need to add at least <target>/</target> as we previously discussed
