Hello,
Recently I’m learning QEMU storage. I think the two structures are very important, BlockBackend and BlockDriver. Usually BlockBackend resides in the block device structure like disk, flash etc and the block device is storage device seen by guest OS and driver. BlockDriver will handle the stuff with host. Hope my understanding isn’t wrong.
And vvfat is BlockDriver, can I understand it as: it is constructing a raw disk image (based on the host directory) which can be read by guest? If my bare meta guest setup a fat filesystem, the raw disk image can be read and write correctly?
Thanks a lot
