V2 -> V3:
move the virDomain.metadata and virDomain.setMetadata to model/utils.py
add testcase
V1 -> V2:
libvirt also support virDomain.metadata and virDomain.setMetadata two api.
use virDomain.metadata to get the user and group.
use virDomain.setMetadata to set the user and group.
ShaoHe Feng (3):
Add two function to set and get domain xml metadata
bug fix: get user and group when vm is living.

----------------------------------------<br>
<br>
During the first development, I noticed the virDomain.metadata and
virDomain.setMetadata does not work <br>
well in all libvirt versions. <br>
<br>
While using those functions, some libvirt versions will report: <br>
<br>
libvir: QEMU Driver error : argument unsupported: QEMU driver does
not support<metadata> element <br>
<br>
But if you manually get and set metadata element, libvirt works
fine. <br>

I went through libvirt log I find:<br>

commit 21d13ddc5d2e1ba24fec401fd7aec0f33f0fecf0<br>

<br>
qemu: Add support for virDomainGetMetadata and
virDomainSetMetadata<br>
<br>
And in this patch:<br>
<br>
+ if (flags & VIR_DOMAIN_AFFECT_CONFIG) {<br>
+ switch ((virDomainMetadataType) type) {<br>
+ case VIR_DOMAIN_METADATA_DESCRIPTION:<br>
+ VIR_FREE(persistentDef->description);<br>
+ if (metadata &&<br>
+ !(persistentDef->description =
strdup(metadata)))<br>
+ goto no_memory;<br>
+ break;<br>
+ case VIR_DOMAIN_METADATA_TITLE:<br>
+ VIR_FREE(persistentDef->title);<br>
+ if (metadata &&<br>
+ !(persistentDef->title = strdup(metadata)))<br>
+ goto no_memory;<br>
+ break;<br>
+ case VIR_DOMAIN_METADATA_ELEMENT:<br>
+ qemuReportError(VIR_ERR_ARGUMENT_UNSUPPORTED, "%s",<br>
+ _("QEMU driver does not support"<br>
+ "<metadata> element"));<br>
+ goto cleanup;<br>
<br>
So in first version METADATA_ELEMENT is not supported for set and
get, and late after release 1.1.2 released(my ubuntu 13.10 is
1.1.1-0ubuntu8.5), metadata_element is handled:<br>
<br>
commit ac38bff077642daa17f9a82480062ebef4c11a7b<br>
Author: Peter Krempa <a class="moz-txt-link-rfc2396E" href="mailto:pkrempa@redhat.com"><pkrempa@redhat.com></a><br>
Date: Fri Sep 6 17:34:43 2013 +0200<br>
<br>
conf: Add support for requesting of XML metadata via the API<br>
<br>
So instead of using VIR_DOMAIN_METADATA_ELEMENT, I guess we can use
metadata_description, so that we can set this in live time, or we
can do as Aline did as a workaround until release 1.1.2 is on all of
our supported version?<br>
<br>
What do your say?<br>
