The latest vhost-user changes changed the VHOST_SET_MEM_TABLE handling.
Now the memory regions are mapped from dev->mem. There is an error when calling
qemu_get_ram_fd with reg->guest_phys_addr. The right approach is to find the
ram_addr_t
corresponding to the userspace_addr using qemu_ram_addr_from_host first.
Thanks to Paolo Bonzini for poinitng the real problem.
The related vhost-user qtest is also updated to reflect the changes in
vhost-user message structures.
Changes since v1:
- dropped the patches 1 and 2 and just fixed the "real issue"
