And we have verified related migration features such as snapshot and live migration. A few weeks ago, we submitted RFC patches about supporting RISC-V migration based on kvm accel: https://www.spinics.net/lists/kvm/msg223605.html. And we found that tcg accelerated migration can be supported with a few changes. Most of the devices have already implemented the migration interface, so, to achieve the tcg accelerated migration, we just need to add vmstate of both cpu and sifive_plic.
