Description Peng Huang 2009-04-13 09:30:05 UTC

Description of problem:
qemu-kvm can not execute winxp vm with -vga std or -vga vmware

Version-Release number of selected component (if applicable):
qemu-0.10-7.fc11.x86_64

How reproducible:


Steps to Reproduce:
1. Use a winxp disk image to start qemu-kvm with -vga std or -vga vmware
2. 
3.
  
Actual results:
$ sudo qemu-kvm -vga std -boot c -hda winxp.raw
create_userspace_phys_mem: Invalid argument
kvm_cpu_register_physical_memory: failed


Expected results:



Additional info:
I checked the code. the problem is because of qemu register a vga bios mem region without 4k mem align. If I change the mem align to 4K, qemu-kvm can execute Linux vm with -vga std successfully. But for winxp, I can see the bios screen, but can not boot up winxp successfully.

Ah, sorry Peng - I see it was you that started the discussion on qemu-devel with a patch :-)
