Description Curtis Matthews 2017-08-09 14:20:33 EDT
Description of problem:  Patching appliances ( to RHEL 7.4 causes the appliances to lose the static network config upon reboot.  No CFME packages were updated with this patch cycle.

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

How reproducible:  Every time

Steps to Reproduce:
1.  yum update
2.  reboot

Actual results:  Update completes successfully.  Entering appliance_console shows correct network configuration prior to reboot.  Reboot reverts system to DHCP.

Expected results:  Update and reboot does not modify the network configuration.

Additional info:  Upon resetting the network configuration, a file is created, /etc/cloud/cloud.cfg.d/99_mig_disable_network_config_change.cfg with the contents of "network: {config: disabled}".  If you manually create this file prior to rebooting, the network config is preserved.

Needinfo flag is set but I'm unsure of what is needed.  Please elaborate.
Comment 7 Brandon Dunne 2017-08-15 12:16:20 EDT
The bug was changed to ON_DEV because I was investigating the issue.  I was unable to reproduce the problem, so I added the "needinfo?" and asked if there were any other steps required to reproduce the problem.

Are the network configuration files deleted during the "yum update" or during the reboot?
Comment 10 Curtis Matthews 2017-08-22 23:05:04 EDT
The network configuration survives the yum update and is lost during the reboot.  The cloud-init package is being updated during this upgrade, which I'm guessing is where the issue lies.
