Yea; I vaguely recall that happening. Quite unfortunate.

This is what it says:
Section "PIIX4_PM" Section "PIIX4_PM" Description "piix4_pm": minimum version
error: 2 < 3
Which means qemu-2.1 expects a minimum version of 3, but qemu-kvm-1.0
is sending it version 2. Now even though they may be compatible,
version-number-wise they're not, as the dest qemu will also complain
about.
