Guest hast not initialized the display (yet)

gebi1 · December 11, 2024, 8:51pm

LG runs great on my GVT-g setup. But one issue remains. After starting the VM the boot process is interrupted by 60s showing Guest hast not initialized the display (yet). This message appears after adding the mdev device. After this delay, the boot process continues normally. It’s not a big issue but to fix it would be nice…

Here the VM configuration:

Where’s the VBIOS for that mdev device, either captured from the host while running or from SeaBIOS project? (see the comments on this tutorial via this thread). More details are available at the relevant page of the Arch Linux Wiki

You may also need the parameter x-igd-opregion=on for the mdev.

this is because the mdev is the primary GPU, and is being initialised as the primary instead of the virtual spice video device by the guest BIOS. There is no solution to this in your scenario.

Thanks for the clarification;-

This is a bit off-topic, but the boot process does work normally when using BIOS firmware. But then I ran into another problem: the LG host on Win10 is reporting a random UUID. Then, I got a spice error: You have connected SPICE to the wrong guest. Interestingly, sometimes the reported UUID is 00000000-0000-0000-0000-000000000000. Then - and only then - everything works fine and spice connects!
As far as I know, B6 did not check the UUID (I have to check it after a downgrade). By the way, I don’t know how the UUID Looking Glass uses for SPICE is generated. Is there a way to correct the VM config? Or would it be possible to implement a command line option, to ignore the UUID?
Here is a terminal log, when the spice connection works:
