Description Peng Huang 2009-04-13 05:30:05 EDT
Description of problem:
qemu-kvm can not execute winxp vm with -vga std or -vga vmware

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. Use a winxp disk image to start qemu-kvm with -vga std or -vga vmware
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 :-)
