Sometime you need to mount qcow2 image without running it . 

install 

apt-get install qemu-utils

Now 

(Note) it needs FULL path to qcow2 image

qemu-nbd -c /dev/nbd0 /scratch/vm/Debian-6.0.6-x86_64-rOCCI.qcow2 

Now you can see partitions 

fdisk -l /dev/nbd0

Disk /dev/nbd0: 8589 MB, 8589934592 bytes

255 heads, 63 sectors/track, 1044 cylinders, total 16777216 sectors

Sector size (logical/physical): 512 bytes / 512 bytes

I/O size (minimum/optimal): 512 bytes / 512 bytes
