Added the support of multi reboot handle from common

OpTestInstallUtil.py
OpTestSOL.py (Handling exception)

Error-1

This code is getting error on 2nd reboot, This is the error -->

code (common_utility)

if reboot and (req_args or req_remove_args):

Reboot the host for the kernel command to reflect

if reboot_cmd: raw_pty = self.cv_SYSTEM.console.get_console()
raw_pty.sendline("reboot") raw_pty.expect("login:", timeout=900)

After the first reboot, framework re-establishes console/SSH.

When try to reboot a 2nd time, self.cv_SYSTEM.console.get_console() is giving stale or HMC session, not the OS console.

So Adopt these changes in commonUtility

while reboot

1)Close stale console

2)Reopen it

3)Then reboot

Code changes to

if reboot and (req_args or req_remove_args):
if reboot_cmd:
# Always reopen console fresh to avoid stale session after first reboot
self.cv_SYSTEM.console.close() # <-- add this
raw_pty = self.cv_SYSTEM.console.get_console()

    raw_pty.sendline("reboot")
    login_patterns = [
        "login:", "root login:", "Ubuntu login:", "Password:",
    ]
    raw_pty.expect(login_patterns, timeout=900)

After changing the commonUtility hitting another issue

Before calling self.cv_SYSTEM.console.close() ,must stop the SOL reader thread cleanly

So added exception in OpTestSOL.py --> Done changes

Below we are anyway opening new console, is it really required?

Also, when reboot is executed, all the consoles will become inactive anyway right?

Are you facing issues with only "login:" prompt?

Trying to understand why we need login_patterns. If its really needed, can you use re expression to match any prompt ending with login:
