This is a series of patches to libnbd and nbdkit adding AF_VSOCK support. On the host side it allows you to start an nbdkit instance which listens on a virtio-vsock socket: $ ./nbdkit -fv --vsock memory 1G ... nbdkit: debug: bound to vsock 2:10809 On the guest side you can then use libnbd to connect to the server: $ ./run nbdsh -c 'h.connect_vsock(2, 10809)' -c

We could add it, but equally client code can just check AF_VSOCK the same way that libnbd does, ie with a configu...

Previous discussion: https://www.redhat.com/archives/libguestfs/2019-August/msg00102.html Last night I experimentally added support for URIs that contain the query parameter tls-psk-file, as part of rewriting the tests to cover more of the URI code. So you can now have a URI like: nbds://alice@localhost/?tls-psk-file=keys.psk However there's an obvious security problem here because now
