migrating a vm from old qemu-kvm 0.12.5 to new qemu-kvm 0.14.1

Hi,

restoring a memory dump created with an old version qemu-kvm 0.12.5 to new 0.14.0 or 0.14.1 does not work for me

looking at the code this is supposed to work vmstate_load() runs through the various sections without errors and the vm is up and running but the guest seems to be crashed

same thing happens if you migrate a vm from old to new

has anybody had success with migrating from old to new ?

any ideas/hints where the problem could be ?

Regards,
Jason
