SYNOPSIS guestfish options commands. WARNINGUsing guestfish in write mode on live virtual machines, or concurrently with other disk editing tools, can be dangerous, potentially causing disk corruption. The virtual machine must be shut down before you use this command, and disk images must not be edited concurrently. Use the ro read only option to use guestfish safely if the disk image or virtual machine might be live. You may see strange or inconsistent results if running concurrently with other changes, but with this option you wont risk disk corruption. DESCRIPTIONGuestfish is a shell and command line tool for examining and modifying virtual machine filesystems. It uses libguestfs and exposes all of the functionality of the guestfs API, see guestfs3. Guestfish gives you structured access to the libguestfs API, from shell scripts or the command line or interactively. If you want to rescue a broken virtual machine image, you should look at the virt rescue1 command. EXAMPLESAs an interactive shell guestfish. Welcome to guestfish, the guest filesystem shell for. Type help for a list of commands. Created by anaconda. From shell scripts. Create a new etcmotd file in a guest or disk image guestfish lt lt EOF. Welcome, new users. EOFList the LVM logical volumes in a disk image guestfish a disk. EOF. EOFList all the filesystems in a disk image guestfish a disk. EOF. list filesystems. EOFOn one command line. Update etcresolv. Edit bootgrubgrub. Mount disks automatically. Use the i option to automatically mount the disks from a virtual machine guestfish ro a disk. Another way to edit bootgrubgrub. As a script interpreter. Create a 1. 00. MB disk containing an ext. M. part disk devsda mbr. Start with a prepared disk. An alternate way to create a 1. MB disk called test. N fs. To list what is available do guestfish N help less. Remote drives. Access a remote disk using ssh guestfish a ssh example. Remote control eval guestfish listen. OPTIONS help. Displays general help on options. Lists all available guestfish commands. CMD cmd help CMDDisplays detailed help on a single command cmd. IMAGE add IMAGEAdd a block device or virtual machine image to the shell. The format of the disk image is auto detected. To override this and force a particular format use the format. Using this flag is mostly equivalent to using the add command, with readonly true if the ro flag was given, and with format. URI add URIAdd a remote disk. See ADDING REMOTE STORAGE. URI connect URIWhen used in conjunction with the d option, this specifies the libvirt URI to use. The default is to use the default libvirt connection. If using the listen option and a csh like shell, use this option. See section REMOTE CONTROL AND CSH below. LIBVIRT DOMAIN domain LIBVIRT DOMAINAdd disks from the named libvirt domain. If the ro option is also used, then any libvirt domain can be used. However in write mode, only libvirt domains which are shut down can be named here. Domain UUIDs can be used instead of names. Using this flag is mostly equivalent to using the add domain command, with readonly true if the ro flag was given, and with format. When prompting for keys and passphrases, guestfish normally turns echoing off so you cannot see what you are typing. If you are not worried about Tempest attacks and there is no one else in the room you can specify this flag to see what you are typing. FILE file FILERead commands from FILE. To write pure guestfish scripts, use usrbinguestfish f formatrawqcow. The default for the a option is to auto detect the format of the disk image. Using this forces the disk format for a options which follow on the command line. Using format with no argument switches back to auto detection for subsequent a options. For example guestfish formatraw a disk. If you have untrusted raw format guest disk images, you should use this option to specify the disk format. This avoids a possible security problem with malicious guests CVE 2. See also add. i inspector. Using virt inspector1 code, inspect the disks looking for an operating system and mount filesystems as they would be mounted on the real virtual machine. Typical usage is either guestfish d myguest ifor an inactive libvirt domain called myguest, or guestfish ro d myguest ifor active domains, readonly, or specify the block device directly guestfish rw a devGuestsMy. Guest i. Note that the command line syntax changed slightly over older versions of guestfish. You can still use the old syntax guestfish ro i disk. Using this flag is mostly equivalent to using the inspect os command and then using other commands to mount the filesystems that were found. Read key or passphrase parameters from stdin. The default is to try to read passphrases from the user by opening devtty. Fork into the background and listen for remote commands. See section REMOTE CONTROL GUESTFISH OVER A SOCKET below. Connect to a live virtual machine. Experimental, see ATTACHING TO RUNNING DAEMONS in guestfs3. Mount the named partition or logical volume on the given mountpoint. If the mountpoint is omitted, it defaults to. You have to mount something on before most commands will work. If any m or mount options are given, the guest is automatically launched. If you dont know what filesystems a disk image contains, you can either run guestfish without this option, then list the partitions, filesystems and LVs available see list partitions, list filesystems and lvs commands, or you can use the virt filesystems1 program. The third and rarely used part of the mount parameter is the list of mount options used to mount the underlying filesystem. If this is not given, then the mount options are either the empty string or ro the latter if the ro flag is used. By specifying the mount options, you override this default choice. Probably the only time you would use this is to enable ACLs andor extended attributes if the filesystem can support them m devsda. Using this flag is equivalent to using the mount options command. The fourth part of the parameter is the filesystem driver to use, such as ext. This is rarely needed, but can be useful if multiple drivers are valid for a filesystem eg ext. Enable QEMU user networking in the guest. N FILENAMETYPE new FILENAMETYPE Nhelp. Prepare a fresh disk image formatted as TYPE. This is an alternative to the a option whereas a adds an existing disk, N creates a preformatted disk with a filesystem and adds it. See PREPARED DISK IMAGES below. Disable autosync. This is enabled by default. See the discussion of autosync in the guestfs3 manpage. Dont tab complete paths on the guest filesystem. It is useful to be able to hit the tab key to complete paths on the guest filesystem, but this causes extra hidden guestfs calls to be made, so this option is here to allow this feature to be disabled. If writes fail to pipe commands see PIPES below, then the command returns an error.
