hi,all
from the aspect of qemu, there are file and block disk type,
what is the final difference between the two types ?
if its type is block and source is volume or physical disk, who finally read/write the disk?
i thought block is raw format, so raw driver will do the actual r/w, am i right?
if so qemu r/w using fileio no matter what disk type it is ?
what is the call flows when disk type is block when vm r/w?
thanks
