Currently the qemu default cache size is 32MB , enough to handle 256 GB
images.
so, I'm not sure It'll make so much difference. even if user have a lot
of 512GB images (100images for example), 50TB, it'll add an extra
100x32MB = 3GB memory .
sure, if user have 100 imagesx8TB, 800TB stockage on 1 host, It'll
increase memory to around 100x1GB = 100Gb memory. ^_

and if we use something calculated from the size of the disk, it'll not
help to limit global memory usage.
