You may need to mount a qemu RAW image to your linux system for various reasons. To do so, please follow the next steps:
Mounting a raw image file with one partition is pretty straight forward. Assuminug the RAW image file name is VirtualMachineImage.raw and the directory to mount the disk is /mnt
losetup /dev/loop0 VirtualMachineImage.raw kpartx -a /dev/loop0 mount /dev/mapper/loop0p1 /mnt
Now you can go to the directory /mnt and you’ll find all files inside the RAW image.
To mount a qcow2 file, assuming the qcow2 file name is VirtualMachineImage.qcow2 proceed as follows:
modprobe nbd max_part=63 qemu-nbd -c /dev/nbd0 VirtualMachineImage.qcow2 mount /dev/nbd0p1 /mnt
