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 Takashi Kajinami 2019-08-26 00:44:25 UTC

Description of problem:

When we launch RHEL7.6 or 7.7 VM on OpenStack, we see that cloud-init fails to persist metadata with the following error.

""__init__.py[WARNING]: Error persisting instance-data.json: 'utf8' codec can't decode byte 0xXX in position N: invalid continuation byte"

The failure is happening in the wrong handling in random_sheed metadata, and there is existing bug report[1] on launchpad about this issue.
[1] https://bugs.launchpad.net/cloud-init/+bug/1801364


How reproducible:
Always

Steps to Reproduce:
1. Launch RHEL7.7 instance on OpenStack, with random_seed configured

Actual results:
cloud-init fails to persist instance data with error

Expected results:
cloud-init succeeds to persist instance data without error
