From: Andy King <ack...@vmware.com> ** Introduce VM Sockets ***
In an effort to improve the out-of-the-box experience with Linux kernels for VMware users, VMware is working on readying the VM Sockets (VSOCK, formerly VMCI Sockets) (vmw_vsock) kernel module for inclusion in the Linux kernel. The purpose of this post is to acquire feedback on the vmw_vsock kernel module. Unlike previous submissions, where the new socket family was entirely reliant on VMware's VMCI PCI device (and thus VMware's hypervisor), VM Sockets is now _mostly_ separated out into two parts: o Core socket code, which is transport-neutral and invokes transport callbacks to communicate with the hypervisor. o A VMCI transport, which communicates over VMCI with the VMware hypervisor. This should provide a path to introducing additional transports, for example virtio, with the ultimate goal being to make this new socket family hypervisor-neutral.
