vSockets are used for host<>guest communication using the standard socket API. They already supported in the mainline 
Linux kernel and can be used in VMware VMs.

There is an ongoing work to implement a virtio transport which will add vSockets support to QEMU. Additionally, it 
will include a vsockmon device that will allow the host to monitor the data exchanged through vSockets.

The vsockmon device has already been reviewed and its header is already defined:

https://github.com/GerardGarcia/linux/blob/vsockmon/include/uapi/linux/vsockmon.h

So what follows the header?  I.e., what's the payload of a vSocket packet?
