Motsatti,

I checked again, guest still booting stop at the loading scroll bar. Let
find what difference between ours.
Can you check if your reproduce steps:
1) 32-bit WinXP
1) acpi on
2) shadow mode

Windows guest did not blue screen with latest KVM commit, but guest hang
at the loading scroll bar. 

This issue only happen on shadow mode. Windows guest can boot up with EPT
mode.

Xudong,

Can you reproduce the problem with latest git repositories? 

The BSOD screenshot is truncated, the error number is not present.
