In RHEVM TUI to set password, we also can reproduce this issue. 2. In CIM TUI to set password, we also can reproduce this issue. 3. And when upgrading via TUI, then set new password when TUI upgrade, then still encounter this error and password will not set new after upgrade.
correct myself here for bug description version info: rhev-hypervisor7-7.1-20150728.1 ovirt-node-3.2.3-14.el7 rhev-hypervisor-6-6.7-20150728.0 ovirt-node-3.2.3-14.el6
Workaround: 1. If you encounter the error 2. Drop to shell 3. unmount /etc/shadow 4. cp /config/etc/shadow /etc/shadow 5. /usr/libexec/ovirt-config-password 6. Set the password step 6 will set new password successful.
Patch has been tested (on el6 and el7) as follows: 1. Clean install 2. Login to TUI 3. Set a new password on the security page 4. Reboot 5. Login to TUI 6. set password again 7. Reboot 8. Login to TUI Results: After 3: Setting password worked After 5: Login works After 6: Setting password worked After 8: Login works

I can not reproduce this during RHEV-H 6.7-20150828 installation, but for password issue, we have one bug on upgrade flow: Bug 1263648 - [7.2_3.5][node]"Error replacing '/etc/passwd': Device or resource busy" occurs when upgrade from 7.1 to RHEV-H 7.2.
