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

qemu: Add support for virDomainGetMetadata and virDomainSetMetadata
And in this patch:
+ if (flags & VIR_DOMAIN_AFFECT_CONFIG) {
+ switch ((virDomainMetadataType) type) {
+ case VIR_DOMAIN_METADATA_DESCRIPTION:
+ VIR_FREE(persistentDef->description);
+ if (metadata &&
+ !(persistentDef->description = strdup(metadata)))
+ goto no_memory;
+ break;
+ case VIR_DOMAIN_METADATA_TITLE:
+ VIR_FREE(persistentDef->title);
+ if (metadata &&
+ !(persistentDef->title = strdup(metadata)))
+ goto no_memory;
+ break;
+ case VIR_DOMAIN_METADATA_ELEMENT:
+ qemuReportError(VIR_ERR_ARGUMENT_UNSUPPORTED, "%s",
+ _("QEMU driver does not support"
+ "<metadata> element"));
+ goto cleanup;
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:

conf: Add support for requesting of XML metadata via the API
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?
What do your say?
