"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

Edit your VM and add new "Serial" device then you will see VM's output

Hello how to solve the problem

[naveenrajm7]

This is an even bigger problem when you are installing the OS. You will not have the ability to choose options or see progress for automated installs.
As indicated above, I get around this problem by having a serial port to the VM.
I will add either 'built-in terminal' or 'ptty device' (which I'll see via screen) and see the logs/choose the options, all while there is another screen which says "Display output is not active". Once the installation is complete, the "Display output is not active" will disappear and we get to see the VM screen.
NOTE: This is not specific to fedora, I have observed this in most VMs (with Display) we built for UTM VM Gallery https://naveenrajm7.github.io/utm-gallery/
