Hi All,

Now, OVMF UEFI can boot on the Xen hvmloader. But, there is no VGA bios for OVMF from the source code hvmloader/ovmf.c in the upstream Xen.
I have tried the vgabios provided by Xen, but I can see nothing through the vnc client or sdl graphic window. Actually, if we check the boot trace log of OVMF, we find that OVMF has booted into the OS installer grub.
When I try the cirrus_vga bios (named OvmfVideo.rom in edk2) provided by OVMF, I can see the OVMF boot successfully through the vnc client or sdl graphic window.

I had specifically skipped this for several reasons:
1) This is not the right way to fix this (not including the VGA blob)
2) When I tried, it was working for me so I just assumed tiancore was fixed by using the BAR directly

Maybe Andrei or Jordan can shade a light on tianocore behaviour here.
In the while, can you please explain how to exactly reproduce your issue, posting all the configurations and environment you used?
Do you use the upstream qemu? Could you tell me where to get it and how to setup it? Thanks.



Best Regards,
Bei Guan
