...n and nbdkit is consuming 100% of CPU. In all other respects everything works fine, you can send commands etc. Anyway I tracked the issue down. nbdkit sits in a loop continuously reading stdin, each read(2) call returning EAGAIN. The reason for that is because libnbd opens a socketpair with the SOCK_NONBLOCK option and passes one half directly to the forked subprocess. It's obviously a bug, but I'm not sure if libnbd should be unsetting the SOCK_NONBLOCK option or if nbdkit should be doing it. Maybe both!

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
