What were you trying to do that didn't work?

Install 10B with kernel arg "console=ttyS0".

Please provide the package NVR for which bug is seen:

anaconda 40.22.3.2

How reproducible:

100%

Steps to reproduce

1. Install libvirt qemu-kvm virt-install and reboot

2. virt-install -r 4096 -n debug --vcpus=4 --disk size=10 --location=<installation-tree-url> --console pty --nographics --extra-args \"console=ttyS0\" --os-variant rhel-unknown
   

Expected results

The system boots and starts the anaconda installer

Actual results

The system doesn't start the anaconda installer. It stops right before it at message

Queued start job for default target default.target.
Startup finished in XXXms.

Additional info

1. Regression: the expected result is obtained when installing a RHEL 9.5 tree
2. Happens only on s390x. This might be the case because of the different consoles on this system, [ref ibm docs|*https://www.ibm.com/docs/en/linux-on-systems?topic=wysk-device-console-names-1]
3. For VM installations one can use 'hvc0' instead. Anaconda is also loaded when 'console' kernel parameter is not set
