When I do live migration, in the source and destination host, there are different block devices, but qemu can not detect this. I used virtio as the driver in kvm and in the vdi device in the guest is /dev/vda. So, the vm guest can read different data from the same /dev/vda device.
It's probably the guest kernel (not QEMU) that is caching data from the source's /dev/vda. What you are doing is not a valid usage of migration. What are you trying to do?
