Doc Type: Deprecated Functionality
Doc Text:
*libguestfs* can no longer inspect ISO installer files The *libguestfs* library does no longer support inspecting ISO installer files, for example using the *guestfish* or *virt-inspector* utilities. Use the "osinfo-detect" command for inspecting ISO files instead. This command can be obtained from the _libosinfo_ package.

Description YongkuiGuo 2018-04-09 06:05:56 UTC
Description of problem:

The list returned was empty after executing the inspect-os command with libguestfs-1.38 on rhel7.5 host.

Version-Release number of selected component (if applicable):

How reproducible:


1. On rhel7.5 host
#guestfish -a RHEL-Server-7.4-x86_64-latest.iso
><fs> run
><fs> list-filesystems
/dev/sda1: iso9660
/dev/sda2: vfat
><fs> inspect-os

Actual results:
The returned result of inspect-os was empty.

Expected results:
The inspect-os command should be able to return the disk list.

Additional info:
The virt-inspector also cannot display the operating system info.

Comment 2 Richard W.M. Jones 2018-04-09 07:35:42 UTC
Yes we upstream removed the ability to inspect ISOs.  Unfortunately
I forgot to document this in the release notes, but the commit is:


This is a regression but not one we're likely to want to fix.  It's
much better if given an ISO to use the libosinfo command:

  osinfo-detect --type=media RHEL-Server-7.4-x86_64-latest.iso
