This section describes tools that are simpler equivalents to using guestfish to view and edit guest virtual machine disk images.
virt-cat is similar to the guestfish
download command. It downloads and displays a single file to the guest virtual machine. For example:
# virt-cat RHEL3 /etc/ntp.conf | grep ^server
server 127.127.1.0 # local clock
virt-edit is similar to the guestfish
edit command. It can be used to interactively edit a single file within a guest virtual machine. For example, you may need to edit the
grub.conf file in a Linux-based guest virtual machine that will not boot:
# virt-edit LinuxGuest /boot/grub/grub.conf
virt-edit has another mode where it can be used to make simple non-interactive changes to a single file. For this, the -e option is used. This command, for example, changes the root password in a Linux guest virtual machine to having no password:
# virt-edit LinuxGuest /etc/passwd -e 's/^root:.*?:/root::/'
virt-ls is similar to the guestfish
find commands. It is used to list a directory or directories (recursively). For example, the following command would recursively list files and directories under /home in a Linux guest virtual machine:
# virt-ls -R LinuxGuest /home/ | less
