[Qemu-devel] start qemu failed with --enable-kvm -vga std

[Peng Huang]

Hi,

The HEAD version qemu can not execute a VM with --enable-kvm -vga std or -vga vmware on kernel 2.6.29.1-46.fc11.x86_64. I found it is because of qemu call cpu_register_physical_memory with a wrong size. Below patch can fix it on my box. Please test it.

Regards,
Peng Huang
