The vhost-user-vsock device can be used to implement the virtio-vsock device emulation in user-space. An use case might be Kata, where they prefer to emulate devices in user-space. The first patch creates a new vhost-vsock-common parent class with the common code usable for both vhost-vsock and vhost-user-vsock devices. The other patches add the vhost-user-vsock base device and its PCI version. I also implemented a vhost-user-vsock [1] (still WiP) application written in Rust using crates from Cloud Hypervisor. The application implements the Firecracker hybrid vsock (vsock over unix domain socket) [2] The vhost-user-vsock-pci device can be tested following these steps: # build vhost-user-vsock application git clone https://github.com/stefano-garzarella/cloud-hypervisor.git git checkout vhost-user-vsock cargo build # start vhost-user-vsock ./target/debug/vhost_user_vsock \ --vsock-backend guest_cid=4,uds_path=/tmp/vm4.vsock,sock=/tmp/vhost4.socket # start QEMU qemu-system-x86_64 -m 1G -smp 2 -cpu host -M q35,accel=kvm \ ... \ -chardev socket,id=char0,reconnect=0,path=/tmp/vhost4.socket \ -device vhost-user-vsock-pci,chardev=char0 -monitor stdio # Guest listening guest$ nc --vsock -l 1234 host$ nc -U /tmp/vm4.vsock CONNECT 1234 # Host listening host$ nc -l -U /tmp/vm4.vsock_1234 guest$ nc --vsock 2 1234 [1] https://github.com/stefano-garzarella/cloud-hypervisor.git (vhost-user-vsock branch) [2] https://github.com/firecracker-microvm/firecracker/blob/master/docs/vsock.md Stefano Garzarella (3): vhost-vsock: add vhost-vsock-common abstraction virtio: add vhost-user-vsock base device virtio: add vhost-user-vsock-pci device configure | 3 + include/hw/virtio/vhost-user-vsock.h | 36 ++++ include/hw/virtio/vhost-vsock-common.h | 47 ++++ include/hw/virtio/vhost-vsock.h | 11 +- hw/virtio/vhost-user-vsock-pci.c | 84 ++++++++ hw/virtio/vhost-user-vsock.c | 181 ++++++++++++++++ hw/virtio/vhost-vsock-common.c | 258 ++++++++++++++++++++++ hw/virtio/vhost-vsock.c | 283 ++++--------------------- hw/virtio/Makefile.objs | 4 +- 9 files changed, 656 insertions(+), 251 deletions(-) create mode 100644 include/hw/virtio/vhost-user-vsock.h create mode 100644 include/hw/virtio/vhost-vsock-common.h create mode 100644 hw/virtio/vhost-user-vsock-pci.c create mode 100644 hw/virtio/vhost-user-vsock.c create mode 100644 hw/virtio/vhost-vsock-common.c
