same reason as this bug: https://bugs.launchpad.net/qemu/+bug/882358
This is because kvm is not enabled when starting guest by default even if I add
KVM support when configuring qemu.
Now it got fixed by the following commit.

Revert "qemu-kvm: set default accelerator via target.conf"
This reverts commit a5c40eb1aa929a03157252db7337bc4ddd2435be.
Jan says:
"Unless you fully install qemu, that conf is not picked up (or an older
version is used). I'd still like to see this working with qemu started
from a build directory..."

Title:
64-bit windows guest cannot boot up
Status in QEMU:
Fix Released
Bug description:
qemu.git (memory/queue branch) commit:
6cc7686696f73ae87cadef4450776a488b0e0c8b
or qemu.git (master branch) commit: 8843cf40c0f482949e6ae9d0119e45d6b96fe890
kvm.git commit: 7f914d61cd2156e34a7852462bb4932621f33a34
64-bit Windows guest cannot boot up, but 32-bit windows guest can boot
up successfully. For Win7, it will show blue scream of death when
booting up. For Windows XP, the guest hangs without blue screen when
booting up. But when I use qemu-kvm.git with commit a040d28b, I won't
meet this issue. I did the comparative test in the same box and using
the same command line to create a guest.
I found this bug in memory/queue branch of qemu.git on September 21st.
As some codes in memory branch were merged into master branch, the
master tree of qemu.git also has this issue now.
I found the following git log in master tree. And that merger maybe
introduced this issue in master tree.
commit 36f490b176afab3096e9c2877b365354f67e269d
