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):
libguestfs-1.38.0-1.el7.x86_64
qemu-kvm-1.5.3-156.el7.x86_64
kernel-3.10.0-862.el7.x86_64
libvirt-3.9.0-14.el7.x86_64

How reproducible:
100%


Steps:

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
><fs>

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.

Yes we upstream removed the ability to inspect ISOs.  Unfortunately
I forgot to document this in the release notes, but the commit is:

  https://github.com/libguestfs/libguestfs/commit/65cfecb0f5344ec92d3f0d3c2ec0538b6b2726e2

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
