L<guestfish(1)> is a more powerful, lower level tool which you can use

Using C<virt-cat> is approximately equivalent to doing:
guestfish --ro -i -d domname download file -
where C<domname> is the name of the libvirt guest, and C<file> is the
full path to the file. Note the final C<-> (meaning "output to
stdout").
The command above uses libguestfs's guest inspection feature and so
does not work on guests that libguestfs cannot inspect, or on things
like arbitrary disk images that don't contain guests. To display a
file from a disk image directly, use:
guestfish --ro -a disk.img -m /dev/sda1 download file -
where C<disk.img> is the disk image, C</dev/sda1> is the filesystem
within the disk image to edit, and C<file> is the full path to the
file.

L<guestfish(1)> is a more powerful, lower level tool which you can use
when C<virt-edit> doesn't work.
Using C<virt-edit> is approximately equivalent to doing:
guestfish --rw -i -d domname edit /file
where C<domname> is the name of the libvirt guest, and C</file> is the
full path to the file.
The command above uses libguestfs's guest inspection feature and so

where C<disk.img> is the disk image, C</dev/sda1> is the filesystem

C<virt-edit> cannot create new files. Use the guestfish commands
C<touch>, C<write> or C<upload> instead:
guestfish --rw -i -d domname touch /newfile
guestfish --rw -i -d domname write /newfile "new content"
guestfish --rw -i -d domname upload localfile /newfile
C<virt-edit> cannot edit multiple files, but guestfish can
do it like this:
