Hello guys, In commit d021c344051af91 (VSOCK: Introduce VM Sockets), VMware added VM Sockets support. VM Sockets allows communication between virtual machines and the hypervisor. VM Sockets is able to use different hyervisor neutral transport to transfer data. Currently, only VMware VMCI transport is supported. This series introduces virtio transport for VM Sockets. Any comments are

This patch series adds a virtio transport for AF_VSOCK (net/vmw_vsock/). AF_VSOCK is designed for communication between virtual machines and hypervisors. It is currently only implemented for VMware's VMCI transport. This series implements the proposed virtio-vsock device specification from here: http://comments.gmane.org/gmane.comp.emulators.virtio.devel/855 Most of the work was done by

Hello guys, This was V2 of the virtio-vsock back in last October. I do not have time to work on it since then. People are asking the latest status of virtio-vsock from time to time, so I'm sending out the code for people who are interested in. Feel free to grab the code and work on it if you want. In commit d021c344051af91 (VSOCK: Introduce VM Sockets), VMware added VM Sockets support. VM

The virtio-vsock device specification is not finalized yet. Michael Tsirkin voiced concerned about merging this code when the hardware interface (and possibly the userspace interface) could still change. Please revert for now. I am working to finalize the virtio-vsock device specification and at that point the interfaces will be stable. Stefan Hajnoczi (6): Revert "VSOCK: fix
