High memory, above 3 gigabytes. > region: > gpa = 0xFFFC0000 > size = 262144 > ua = 0x7fc13d200000 This is the BIOS. There shouldn't be any FD for this one, it is not allocated in hugetlbfs. > region: > gpa = 0x0 > size = 655360 > ua = 0x2aaaaac00000 > region: > gpa = 0xC0000 > size = 3220439040 > ua = 0x2aaaaacc0000 Together, it's the first 3 GB of memory. I understand now what you mean. Yeah, the format should be changed to include the offset (why does vhost-user need the ua at all? perhaps the offset can replace the ua). > BTW Any idea what to do with region 2, it doesn’t look like the one belonging > to the same place, but qemu_get_ram_fd() returns same FD for it. This must be a bug. I would have expected qemu_get_ram_fd to return -1 here, so no descriptor should be passed to vhost-user. Paolo
