RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description Xianghua Chen 2016-06-02 08:31:56 UTC 
Description of problem:
 virt-get-kernel prompts an 'invalid value' error when using --format auto.


Version-Release number of selected component (if applicable):
libguestfs-1.32.4-3.el7.aarch64
libguestfs-tools-c-1.32.4-3.el7.x86_64

How reproducible:
Always

Steps to Reproduce:
1.  Prepare an rhel7 image:  rhel7.1-sr1.qcow2
2.  # virt-get-kernel --add rhel7.1-sr1.qcow2  --format auto -v -x
libguestfs: trace: set_verbose true
libguestfs: trace: set_verbose = 0
libguestfs: trace: add_drive "/home/xchen/my-images/rhel7.1-sr1.qcow2" "readonly:true" "format:auto" "protocol:file"
libguestfs: creating COW overlay to protect original drive content
libguestfs: trace: get_tmpdir
libguestfs: trace: get_tmpdir = "/tmp"
libguestfs: trace: disk_create "/tmp/libguestfstyNuRg/overlay1" "qcow2" -1 "backingfile:/home/xchen/my-images/rhel7.1-sr1.qcow2" "backingformat:auto"
libguestfs: trace: disk_create = -1 (error)
libguestfs: trace: add_drive = -1 (error)
virt-get-kernel: error: libguestfs error: invalid value for backingformat 
parameter 'auto'
libguestfs: trace: close
libguestfs: closing guestfs handle 0x1fc82e0 (state 0)
libguestfs: command: run: rm
libguestfs: command: run: \ -rf /tmp/libguestfstyNuRg


Actual results:
virt-get-kernel: error: libguestfs error: invalid value for backingformat
parameter 'auto

Expected results:
virt-get-kernel should auto-detect the format of the disk image and can get kernel and ramdisk from guests successfully.
Or,this option  should be deleted from man page if it is not actually provided.

Additional info:
Comment 1 Pino Toscano 2016-06-08 14:19:34 UTC 
Fixed upstream with
https://github.com/libguestfs/libguestfs/commit/35fa14152245bcae2c0842abf120cd4ec7bd098c
which is in libguestfs >= 1.33.36.
Comment 3 Xianghua Chen 2016-06-28 05:22:55 UTC 
Verified with the packages:
libguestfs-1.32.5-6.el7.x86_64

Verify steps:
1.  Prepare an rhel7 image:  RHEL-Server-7.2-64-hvm.raw
2.  # virt-get-kernel --add  RHEL-Server-7.2-64-hvm.raw --format auto
download: /boot/vmlinuz-3.10.0-327.el7.x86_64 -> ./vmlinuz-3.10.0-327.el7.x86_64
download: /boot/initramfs-3.10.0-327.el7.x86_64.img -> ./initramfs-3.10.0-327.el7.x86_64.img

It finished successfully.

So verified.
