Replace ramfb with virtio-gpu-pci at 2048x1280 and install the viogpudo driver from the VirtIO ISO. ramfb has a fixed mode, and keeping both adapters left Windows with a second, fixed-mode monitor. Windows Setup and the base image have no viogpudo driver, so on the launch that creates the system disk the launcher also adds a ramfb ahead of the config files. The display window shows the first GPU. Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>
Cloud-init seed images
Each operating system has an independent NoCloud configuration and generated
seed.iso:
seediso/
├── debian13/
├── almalinux10/
├── fedora44/
└── ubuntu2604/
Keeping per-OS metadata separate allows each VM to use a distinct hostname and
cloud-init instance-id. Generated ISO files are ignored by Git and are built
automatically by the corresponding launcher when missing.
