hmmm, I checked with the current implement, it works, if I add <cmdline>console=tty0 console=ttyS0,115200n8</cmdline> to generate of domain_configuration.py, it failed:

libvirt: QEMU Driver error : internal error: process exited while connecting to monitor: 2025-11-27T22:45:27.103873Z qemu-system-x86_64: -append only allowed with -kernel option
  Instance startup failed, retrying in 5 seconds...

any clue on how to fix it? 😐
