Virtual machines use grant table hypercalls to setup a share page for inter-VMs communications. These hypercalls are used by all PV protocols today. However, very simple guests, such as baremetal applications, might not have the infrastructure to handle the grant table. This project is about setting up several shared memory areas for inter-VMs communications directly from the VM config file. So that the guest kernel doesn't have to have grant table support to be able to communicate with other guests. This should work on both x86 and ARM.
