[libvirt] virDomainSetMetadata --> qemuDomainSetMetadata

Hi, I have requirement to add <metadata> tag into the libvirt XML from the application. While calling virDomainSetMetadata which internally call qemuDomainSetMetadata (correct me here if I am wrong), I am getting following error: qemuDomainSetMetdata:12623 : argument unsupported: QEMU driver does not support<metadata> element Support for setting and getting <metadata> with special namespace is deliberately added in 0.9.10 of libvirt and I am using 0.9.13. I am surprise that the internal qemu driver is still cribbing out it. I am passing following in my call: Type : VIR_DOMAIN_METADATA_ELEMENT Metadata: "<desc> Some Desc </desc>" Key: "Ronak" uri: "Ronak.com/Ronak/libvirt" Flags: 0 Can someone please help? Thanks, Ronak
