Hi Avi,
I can't restore a guest saved by an older qemu. I wonder if this issue is introduced by some latest commits on the file 'hw/i8254.c'.
The new commit: b5ed4b6f (on Mar 1) I tried to restore a guest using this qemu.
The old commit: 9d636ae7 (on Feb 11) I saved a guest using this qemu.
I got some error when restoring a guest saved by an old qemu now.
[root@vt-nhm9 jay]# qemu-system-x86_64 -smp 4 -m 1024 -hda rhel6u1.qcow -incoming "exec:dd if=save.img"

A good one is something like the following.
[root@vt-nhm9 jay]# ~/qemu-kvm/x86_64-softmmu/qemu-system-x86_64 -smp 4 -m 1024 -hda rhel6u1.qcow -incoming "exec:dd if=save1.img"
