Why virt-install with --noautoconsole option does not reboot guest after the installation is finished?

Issue

• While using a kickstart file with "reboot" specified in the post section of it to get the guest rebooted after installation, running "virt-install" with "--noautoconsole" option to fully automate the installation does not actually reboot the guest after installation is finished.

• On the other hand if  "--nographics" or the default VNC options are used, the process proceeds as normal and the guest is rebooted after completing the kickstart installation.
