New in libguestfs 1.0.72 will be a tool for editing files in a virtual machine.
There’s a million uses for this. Change grub configuration:
# virt-edit mydomain /boot/grub/grub.conf
Edit the message of the day:
# virt-edit mydomain /etc/motd
Change a configuration file:
# virt-edit mydomain /etc/fstab
You get the idea …
For more complex changes, or to edit multiple files, use the libguestfs API or guestfish, but I hope this solves some of the simpler sysadmin tasks.
