Another, hopefully less likely, case is a QEMu bug. If QEMU cannot
correctly restore the VM state from the migration
data stream, you'll get the same error.
Anyway, this definitely looks like libvirt/qemu issue; better be
prepared to file a libvirt bug.
does it happen migrating to *any* CentOS7.3 box?

Bests,
