Inspect VM filesystem
Posted on :: Updated on :: virtualization

Source: https://linux.die.net/man/1/guestfish

To inspect files inside VM disk (qcow2, img or other kinds), install guestfish:

apt install libguestfs-tools

guestfish 
> add-ro debian.qcow2
> run
> help mount-ro

Type help gives you what you should do next. You can copy files to host via copy-out /file/in/qcow2 /host/dir/

Questions

  • There's a way to install os by using qcow2 image (without running the installer). How does that work? #question
