1 * Xen hypervisor reserved-memory binding 2 3 Expose one or more memory regions as reserved-memory to the guest 4 virtual machine. Typically, a region is configured at VM creation time 5 to be a shared memory area across multiple virtual machines for 6 communication among them. 7 8 For each of these pre-shared memory regions, a range is exposed under 9 the /reserved-memory node as a child node. Each range sub-node is named 10 xen-shmem@<address> and has the following properties: 11 12 - compatible: 13 compatible = "xen,shared-memory-v1" 14 15 - reg: 16 the base guest physical address and size of the shared memory region 17 18 - xen,offset: (borrower VMs only) 19 64 bit integer offset within the owner virtual machine's shared 20 memory region used for the mapping in the borrower VM. 21 22 - xen,id: 23 a string that identifies the shared memory region as specified in 24 the VM config file
