Doc Type: Bug Fix
Doc Text:
In certain Red Hat Enterprise Virtualization Hypervisor upgrade conditions, the CIM user is not created correctly, causing errors when CIM is enabled and a password is added. This fix adds validation to the set_password function to ensure that the user is setup and correctly configured prior to setting the password.

Description Meng Liang 2012-09-18 08:23:30 EDT
Description of problem:
CIM could not be set successfully after upgrading from rhev-hypervisor6-6.2-20120605.0.el6_2 to  rhev-hypervisor6-6.3-20120913.0.el6_3 on RHEVM

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

How reproducible:

Steps to Reproduce:
1. Install rhev-hypervisor6-6.2-20120605.0.el6_2
2. register rhevh to rhevm (ic157)
3. upgrade rhevh to rhev-hypervisor6-6.3-20120913.0.el6_3 via RHEVM
4. enable CIM and provide correct password.

Actual results:
Error message(see attached figure) shows press 'ok' to return to the configure page.
Enable CIM and enter password again, empty page shows(see attached figure)
The only way to go back to configure page is press F2 to command line and enter 'exit'

This works correctly with upgrade from media.  testing now with upgrade from rhevm.
Comment 5 Mike Burns 2012-10-12 18:00:43 EDT
Fails with upgrade from RHEV-M. 

The cim user does not exist.  I'm not sure if that is the root cause or not, but it certainly doesn't help.

Thoughts for fixing:

alter cim.py to:

check for the cim user
If it does not exist create it with a command like:

unmount_config /etc/shadow /etc/passwd
useradd -G sfcb -g cim -s /sbin/nologin cim
persist /etc/shadow /etc/password

then proceed with setting password, enabling the service, etc.
