Re: [Qemu-devel] NBD server for QEMU images

The patch available from http://qemu-forum.ipi.fi/viewtopic.php?t=2718
adds a new utility, qemu-nbds, that implements a NBD server

I have been using nbd volumes mounted from inside qemu for filestore
and for swap, both read-write, served from files and from partitions,
with the unmodified standard nbd-server (debian testing version) for
intensive work and it has been faster and more reliable than NFS (not
that that's saying much).

The only thing that doesn't work is the -swap option, which just
hangs, but that proves not to be necessary when swapping onto nbd host
volume from qemu-land, even when stress-testing it.

What problem is solved by a specially modified nbd server?
