similar to: restrict access to host from guestfish

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

Hi, I could not find any option to set iSCSI initiator iqn while using guestfish, although the underlying qemu command has this option. It appears that each time guestfish tries to connect to iSCSI LUN, a randomly generated initiator iqn is being used. This is preventing guestfish to connect to the iSCSI target in our environment as the target allows incoming connection based on the preconfigured

Hi Experts, I am writing a guestfish script . I want to implement conditional logic inside guestfish script. For example , if state.tgz exists in image do something else if onetime.tgz exists in the image do someotherthing . Is it possible to do this within guestfish script. I tried to search a solution for this in guestfish doucmentation but couldn't find anything useful. Thanks in advance

Thank you for the quick response. > Strange way to do this, as libguestfs can do all this. Sorry to ask this (I'm a newly graduated engineer and I new to the virtualization world), but how can libguestfs do all of the above?, do you mean it can create all the partitions inside a new lvm volume or a new raw image?? > Did you copy the syslinux.cfg file into the guest?

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

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?

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

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

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
