Very nice, I've fixed two bullets about the future of the xml-rpc.
I think that we are missing something here: how do we model Vdsm-to-Vdsm
communication, in a binding-blind way? I'm less worried about the
storage-based mailbox used for lvextend requests: my problem is with
Currently, the implementation of the "migrate" verb includes contacting
the remote Vdsm over xml-rpc before issuing the libvirt migrateToURI2
command ('migrationCreate' verb).
A Vdsm user who choose to use the REST binding, is likely to want this to
be implemented this using a REST request to the destination. This means
that the implementation of Vdsm depends on the chosen binding.
The issue can be mitigating by requiring the binding level to provide a
"callback" for migrationCreate (and any other future Vdsm->world requests).
This would complicate the beautiful png at
