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 Richard W.M. Jones 2022-04-11 12:03:25 UTC 
Description of problem:

Virt-v2v has an option to output to a templated JSON file.  It
is currently documented as follows:

        virt-v2v [-i* options] -o json -os DIRECTORY
                               [-oo json-disks-pattern=PATTERN]
    [...]
    OUTPUT TO JSON
       The -o json option produces the following files by default:

        NAME.json                     JSON metadata.
        NAME-sda, NAME-sdb, etc.      Guest disk(s).

       where "NAME" is the guest name.

       It is possible to change the pattern of the disks using the -oo
       json-disks-pattern=... option: it allows parameters in form of "%{...}"
       variables, for example:

        -oo json-disks-pattern=disk%{DiskNo}.img
    [...]

This feature was added for KubeVirt but was never used.

I'm intending to remove this in virt-v2v upstream version 2.2,
but I think we should remove it from virt-v2v in RHEL 9.1 (version 2.0.x).

This will be a kind of regression because the feature is available
in RHEL 9.0, but we don't believe anyone is using it.

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

virt-v2v-2.0.2-1.el9.x86_64
Comment 1 Richard W.M. Jones 2022-04-11 12:04:50 UTC 
Fixed upstream in:

https://github.com/libguestfs/virt-v2v/commit/02e58d54fef14be72078559dae8c7c7a39f7c0f5
https://github.com/libguestfs/virt-v2v/commit/4e6b389b4e27c8d13e57fcaf777d96ad7e08650b

For QE, you can remove any tests of this feature from RHEL 9.
Comment 7 Vera 2022-04-15 06:12:55 UTC 
Reproduced with virt-v2v-1.45.99-2.el9_0.x86_64.

Step1: Check the manual page
# man virt-v2v |grep json
       -o json
           Set the output method to json.
           For -o json, -o local and -o qemu, this is a directory name.  The directory must exist.

Step2: Check in the command
# virt-v2v -o json
[   0.3] Setting up the source: -i libvirt
virt-v2v: error: -i libvirt: expecting a libvirt guest name on the command 
line

If reporting bugs, run virt-v2v with debugging enabled and include the 
complete output:

  virt-v2v -v -x [...]


Verified with virt-v2v-2.0.3-1.el9.x86_64.
Step1: Check the manual page
# man virt-v2v |grep json

Step2: Check in the command
# virt-v2v -o json
virt-v2v: error: unknown -o option: json

If reporting bugs, run virt-v2v with debugging enabled and include the 
complete output:

  virt-v2v -v -x [...]

Moving to Verified.
