The breaking difference seems to be:
$ grep serial /mnt/debian/boot/grub/grub.cfg
$ grep serial /mnt/fedora/boot/grub2/grub.cfg
serial
terminal_input serial
terminal_output serial
And with that hindsight, this can be reproduced also with one-liner:
# Hangs
$ virt-install --name bookworm --ram 40
Tested on Debian Testing VM with nested virtualization enabled and can
be reproduced there as well. Exact steps to reproduce are:
$ sudo apt install vagrant vagrant-libvirt libvirt-daemon-system
virtinst cpu-checker
$ sudo usermod -aG libvirt $USER
$ gnome-sessions-quit # Relogin for group changes
