Back to tcg accelerator.

This looks like a problem, no?

You can't migrate from tcg to KVM.

QEMU 1.0 monitor - type 'help' for more information
(qemu) loadvm /mnt/x.out
Unknown savevm section or instance 'hpet' 0

If I do, on O1,
qemu-system-x86_64 -M pc-0.14 -vnc :1 -m 512 -cdrom 
debian-testing-amd64-businesscard.iso -monitor stdio -hda /mnt/x.qcow2 -net 
user -net nic,model=rtl8139 -S
(qemu) loadvm /mnt/x.out

that succeeds
