Re: [Libvir] libvirt and accessing remote systems



Some highlights from today's investigation into secure RPCs (a topic which I want to bring to a close as soon as possible).

* TI-RPC was suggested as an alternative to SunRPC. The available library has licensing problems which may preclude any integration into libvirt.

* SunRPC over IPv6: tested and working

* Either xmlrpc-c or Curl (which it uses for HTTP connections) cannot manage to do persistent connections, which makes XML-RPC very slow. I haven't yet got to the bottom of why this isn't working, since Curl certainly ought to be able to do keepalives.

* Some performance numbers which you can take with a large grain of salt are available here:

The other issues are written up in the above document for your browsing pleasure.

Rich.
