No, this is a bug I just fixed yesterday in Qemu proper. The next time that Avi
rebases KVM to Qemu (which he said he would do as soon as the fix went into
Qemu), then this should be fixed.

FYI, the problem is basically that the i2c restore on the destination side was
expecting 4 bytes, while the i2c save on the sending side was only sending 1
byte, so they eventually timed out while waiting for each other.
