"Display output is not active" when showing Fedora boot splash screen

[lukehutch]

Describe the issue

Between the bios screen and the Xorg screen, Fedora initializes the display to full resolution, and displays a splash screen, with a spinner. Under UTM with a Fedora guest OS, when this screen is supposed to be displayed, only "Display output is not active" is shown in a low-res font.

This is a bigger problem while installing OS major version updates, because the "Display output is not active" screen may be displayed for several minutes while the system updates after a reboot, and you can't see that it's making progress.

Configuration

• UTM Version: 4.6.4
• macOS Version: 15.2
• Mac Chip (Intel, M1, ...): M4
