Mount a QCOW or VMDK File
There are various utilities for mounting and manipulating qcow and vmdk files. Here we will focus on the libguestfs/guestfish suite of tools, which provides a full interactive shell for manipulating many image types.
The steps below take place in the interactive guestfish shell. Replace image_file with the path of an actual qcow or vmdk file:
# guestfish -a image_file gf# run gf# mount /dev/sda1 / gf# ls / gf# umount-all gf# quit
