+QEMU loadvm causes guest OS freeze
+
+HOST: ubuntu 13.10 x64
+GUEST: winxp sp 3 x86
+
+AFFECT QEMU(tested): v1.5.2, v1.5.3,  v1.6.0, v1.6.1
+
+I compile QEMU by myself with "./configure --target-list=i386-softmmu && make && make install".
+After installing a winxp sp3 into the qemu-system-i386 with command line:
+> qemu-system-i386 -m 512 -hda xp.img -net user -net nic,model=rtl8139 -rtc base=localtime,clock=vm
+
+I use monitor to create a live snapshot: 
+> stop
+> savevm xxx
+> cont
+
+And then I load this snapshot (I also try it in commad line: -loadvm xxx):
+> loadvm xxx
+> cont
+
+After that, the windows system is freeze (don't accept any keyboard or mouse input, although I knew vcpu is still working).
+
+If I compile with -enable-kvm and launch qemu-system-i386 with -enable-kvm, it looks like everything works well.
+I think it is a bug for qemu system.
+
+BTW: freeze is not appearing 100%, but in my test, 95% cases would cause system freeze.
