Re: [Qemu-devel] Re: EFI console stopped working in Qemu 0.14.0

[vagran]

When I trying to specify 64-bit EFI BIOS nothing happens on VGA
nor serial console. It seems that CPU is continuously restarting.

Build and host system is Ubuntu 9.10:
Linux AST-mobile 2.6.31-22-generic-pae #73-Ubuntu SMP Fri Feb 11 18:39:01 UTC 2011 i686 GNU/Linux

Qemu 0.14.0 was built with the following configuration options:
../src/configure --prefix=$PREFIX --target-list=x86_64-softmmu --source-path=../src --enable-kvm
--extra-cflags=-I$PREFIX/include --extra-ldflags=-L$PREFIX/lib

And launched:
qemu-system-x86_64 -L $PHOBOS_PREFIX/share/qemu/phobos64 -bios OVMF.fd -m 768 -cpu core2duo
-vga cirrus -monitor stdio -serial tcp::666,server -s -hdb $PHOBOS_PREFIX/share/qemu/phobos.disk -usb -enable-kvm

OVMF X64 is r11337.

"log cpu_reset" provides this information (continuously in a loop):

I have taken EFI BIOS image from

32-bit version works perfectly. However 64-bit version for some reason

qemu-system-x86_64.
    

Hi.  I was wondering if you could describe the OVMF issue you saw with
qemu-system-x86_64.

I tried 0.14.0 with OVMF X64 (r11337), and it was able to boot to the EFI shell.

I did see an issue while booting the 64-bit Ubuntu 10.10 live-cd, but
occurred on both the legacy (seabios) and uefi (ovmf) firmware.  With
kvm 0.14.0, in both cases the OS boots most of the way, but the
graphics do not start properly when X starts.

Thanks,
