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.
The QEMU driver does support the <metadata> element, but only if you specify it when defining the XML as a whole (eg virDomainDefine). For unknown reasons, the qemuDomainSetMetdata was not implemented to allow for live updating of the <metadata>.
That said, it's a nice beginner's project to implement that functionality, if you'd like to try your hand at writing the patch. -- Eric Blake eblake redhat com +1-919-301-3266 Libvirt virtualization library http://libvirt.org
