For confidential VM on MSHV, GHCB page is the communication method between guest and host. All the CVM exits, VMM needs to read and write to the GHCB page. MSHV provides an option to remap the page to the root partition. This way VMM could directly read and write to the page and skip extra IOCTL and hypercall. This improvement makes the IO 10% faster.
