[Qemu-devel] regarding qcow2metadata

[PANKAJ RAWAT]

Hi all 

qemu-img create -f qcow2 -o preallocation=metadata  guest 8G

The above command will alllocate all the 8GB to the diskimage. 

means 

address@hidden p]# ls -lh

total 1.4M

-rw-r--r-- 1 root root 8.1G Mar  7 12:43 guest

is there is any way to allocate metadata to half size or predefined size ?

i.e 4GB will be allocated and rest 4GB can be allocated dynamically
