--- Begin Message ---
Currently, the qcow2 maximum cache-size is 32MB, enough to handle metadatas
for a 256GB images with 65k cluster size.
if cache-size is not big enough, performance are really bad
This patch increase cache to 1GB, enough to handle 8TB image
with default 32MB cache
fio benchmark 4k randread/write:
256GB image : 32MB cache : 40000 iops
1TB image: 32MB cache: 2500 iops
8TB image: 32MB cache: 2500 iops
1TB image: 1G cache: 40000 iops
8TB image: 1G cache: 40000 iops
the cache-size value is a maximum value, memory is not reserved at vm start.
Also, the metadatas not used are removed from the cache after 10min by default.
