Note that the iso download URL either needs to be updated to reflect a local mirror, or the iso just needs to be present in /tmp/ (line 59)

Hi @infernix, Do you know if it is possible to disable the splashscreen that appears during the early installation phase and says smth about "detected KVM hypervisor instead of ESXi, please confirm by a press of a button"?

That's SUSE's hypervisor compliance checker. To disable it, login to the VCSA and run:
chkconfig --set boot.compliance off
