Hi I want to make a continuous address space between two different guest domains. In particular I want to make a read/write queue, so that both domains, can have an address where they can memcpy from/to data. For example: I want 64k bytes space in kernel to act as a queue. I thought of allocating 16 pages in one domain (16*PAGE SIZE=64k), grant_foreign_access to foreign guest (so I now have 16 gref id's) and map these gref_ids in foreign guest. But I have a question: - How can each side, access the allocated memory as continuous space, and not 16 different spaces? For one page, i alloc_page(...), and then use addr = page_address(page) so I can memcpy to addr bytes up to 4k long. What about more pages?
