Issue with `setenforce Permissive` command in installvm.py script

[vpuliyal]

@PraveenPenguin I setup my dhcp and tftp servers on my lpar. I ran installvm.py script with below arguments and within 5 seconds run was completed.

[root@lktul installpowervm]# python3.7 -u installvm.py --host-ip 9.40.200.xxx --host-name linuxci-lpar1.aus.stglabs.ibm.com --host-gw 9.40.200.1 --host-netmask 255.255.255.0 --host-mac 9a:9e:c4:11:ad:02 --lpar-hmc perfpxxxxx.aus.stglabs.ibm.com --lpar-managed-system perfrainxxxxx --lpar-partition-name linuxci-lpar1 --distro rhel_8.6le_ga --host-disk=nvme-eui.36455630528016980025384100000002 --hmc-profile default_profile --hmc-userid hscroot --hmc-password xxxxxxxxxxxxx

I debug the issue and issue with setenforce Permissive command in installvm.py script.

[root@cihttp rhel]# setenforce Permissive
setenforce: SELinux is disabled
[root@cihttp rhel]# echo $?
1
[root@cihttp rhel]# setenforce Permissive
setenforce: SELinux is disabled
[root@cihttp rhel]# echo $?
1

$? gives you the return value from the last run command. In this case, since SELinux is already disabled, running setenforce Permissive wouldn't go through as it's not needed. I think your script should be handling this case gracefully. It should first check the status of SELinux and then only run these commands if needed.

I've commented below lines in installvm.py script and started now it is working fine. But log files are not showing in log dir.
#cmd = 'setenforce Permissive'
#self.runCommand(self.dhcpSrvCon, cmd)

I don't see any log file under log dir. Because of this reason script is failing.

@PraveenPenguin I debug the log file issue. I've done below changes to "lib/configparser.py" python file.

• import configparser (commented )

• from backports import configparser (included )

To use the backport instead of the built-in version, simply I import it explicitly as a backport.

This will work for lower version of python also.
