I think calling "sh" before "mount" should not confuse guestfish like that: # guestfish (1.20.4 on sles11sp3) Welcome to guestfish, the libguestfs filesystem interactive shell for editing virtual machine filesystems. Type: 'help' for help on commands 'man' to read the manual 'quit' to quit the shell ><fs> add-drive

Nearly any program that writes to standard output can benefit from this sort of fix. Without it, running e.g., ./guestfish --version > /dev/full would exit successfully, even though it got ENOSPC when writing to the full device. That means regular output redirected to a file on a full partition may also fail to be written, and the error ignored. Before: $ guestfish --version >

Is "luks-format" supposed to work with guestfish? Like guestfish <<EOF luks-format /dev/sda4 0 EOF Appearently it lacks an option to give the passphrase programmatically. Was this option skipped on purpose? Olaf

I come across this page libguestfs.org/guestfs-performance.1.html <http://libguestfs.org/guestfs-performance.1.html> This raises my interest. I am currently learning how to benchmark performance qemu. So here is my questions: 1. Can I use guestfish or any tools provided by libguestfs to benchmark qemu? How?

While creating my first guestfish script I noticed an inconsistency in the guestfish(1) man page. The option tgz-out references "tar_out", which does not exist, instead its called "tar-out". The same is true for tgz-in/tar_in. After a quick grep in the code its not clear to me how to resolve this issue. Olaf

This no going to work. AS I told you I need something under guestfish command list not from guestfs commands.

Hi Richard, guestfish shell has an ability to execute commands on the host such as !mkdir local tgz-out /remote local/remote-data.tar.gz What is the best way to restrict access to host from guestfish ? For instance, - Allow readonly access to host.. i.e., !ls is allowed but dont allow !rm or !mkdir - commands such as tgz-out, or copy-out should be able to access just /tmp, but

Hi Nikolay, We use guestfish, so I preferred to use commands supported by guestfish. I tried as below but "realpath" is not working after I have the target path from symlink. --> Check if the path has a symlink. is-symlink path Ex. - is-symlink "/etc/resolv.conf" -> return true --> If it's true then get target link path readlink path ex. - readlink

guestfish --listen necessarily redirects its stdout to /dev/null so as not to interfere with eval. The remote protocol doesn't contain any other provision for collecting stdout for the caller, so executing guestfish --remote will never generate any output. This patch fixes that by forwarding the caller's STDOUT to the listener over the unix socket connection. The listener redirects its

Hi- Is it safe to use the zerofree utility on an ext4 partition inside an LVM with guestfish? I know zerofree works on ext4, but I am unsure about LVM. The info page uses the syntax "zerofree <device>", so using the info page example, could I (safely) do something like the following? $ guestfish Welcome to guestfish, the libguestfs filesystem interactive shell for
