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

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.

Hi Eric, Daniel,
Thanks for the response.
Sure let me try that.
Its defeats the purpose of virDomainSetMetadata if you cant set <metadata> :)
Individual API is written just to support that (obviously along with setting <title>
and <description>).
API takes domain pointer as its first argument which is the return value of
virDomainDefine.
As per my interpretation, you define the XML of <domain> first, grab an handle and
call SetMetadata.
That’s the way I was able to set <title> and <description> and that’s the way
I feel we should set <metadata> as well UNLESS there is a reason for not doing it.
Thanks,
Ronak
