Re: [Libguestfs] [PATCH nbdkit] protocol: Implement NBD_OPT_GO.

So nbdkit never rejects export names (which means it behaves as if all names work, regardless of whether or not it was the name it was configured with, since it exports exactly one volume all the time). An NBD server that exports more than one volume at a time (such as qemu via QMP [but oddly not qemu-nbd], or nbd-server) DOES have to pay attention to export names. And if nbdkit were ever taught to manage more than one export at once, then that would also imply that export names matter. But until then, I don't see nbdkit's behavior as a spec violation. -- Eric Blake, Principal Software Engineer Red Hat, Inc. +1-919-301-3266 Virtualization: qemu.org | libvirt.org
