# qemu-img create -f qcow2 iscsi://10.66.6.82:3260/iqn.2013-11.com.example:storage.disk1.juli.xyz/1 30G

2. Check the info of the image
# qemu-img info iscsi://10.66.6.82:3260/iqn.2013-11.com.example:storage.disk1.juli.xyz/1


Actual results:

Expected results:
disk size: 136K

Additional info:
Install a guest in this image and use "qemu-img info" to check it, disk size is also "unavailable".
Comment 2 Paolo Bonzini 2013-12-03 19:33:01 UTC 
This is okay.  In fact the output for block devices is incorrect and should show "unavailable", but we probably cannot change it without breaking backwards-compatibility.

$ sudo qemu-img info /dev/sda
image: /dev/sda
file format: raw
virtual size: 298G (320072933376 bytes)
disk size: 0
