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.
** Description changed: - qemu.git commit: 6cc7686696f73ae87cadef4450776a488b0e0c8b + 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. BTW, I tested qemu-kvm.git not - qemu.git before kernel.org was down. + 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.
