Qemu / Debian 13 dies

[egandro]

I am using Debian 13 (x86_64)

$ qemu-system-x86_64 --version
QEMU emulator version 10.0.3 (Debian 1:10.0.3+ds-0+deb13u1)
Copyright (c) 2003-2025 Fabrice Bellard and the QEMU Project developers
$ packer build --only=qemu --var virtio_win_iso=./virtio-win.iso ./windows_2025.json

I can connect via VNC and see the installation. At some point qemu just dies.

Can someone give me a hint on how to increase the logging?

Probably it's a resource problem (requested ram in packer file?) - probably it's qemu related.

Thank you.
