(I assumed it would be easier by now) Hi Antoine, QEMU 2.8 will have the vhost-vsock-pci device, you can use qemu.git/master for the time being. You don't need to use my vsock branch anymore. I have also made a copr repository for Fedora available here with qemu-kvm, kernel, and other packages with virtio-vsock support: https://copr.fedorainfracloud.org/coprs/stefanha/vsock/ The nc-vsock utility might be particularly interesting since it lets you try out AF_VSOCK easily (like netcat).
