Hi, Is there any APIs or some XML scheme can passthru a local block device of the host, eg, /dev/sda1 to its running guest OS? Specifically, say there is a block device /dev/sda1 in the host, mount it: mount /dev/sda1 /mnt; ls /mnt: a.file, b.file After passthru, the same /dev/sda1 can be used by the quest os(maybe the dev name is changed): mount /dev/sda1 /mnt; ls /mnt: a.file, b.file.
