IIUC, this is not about the underlying storage, but about whether

always raise VIR_ERR_CONFIG_UNSUPPORTED and return failure to the app
if they request a setting that the hypervisor does not support. Whether
discard is critical or not really depends on your POV, so it is better
not to make such assumptions on behalf of the mgmt app.
So how should the code path error out in this case?
