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
