* migration/ram: ensure write persistence on loading all data to PMEM.Junyan He2018-08-101-0/+6
| | | | | | | | | | | | | Because we need to make sure the pmem kind memory data is synced after migration, we choose to call pmem_persist() when the migration finish. This will make sure the data of pmem is safe and will not lose if power is off.

* mem/nvdimm: ensure write persistence to PMEM in label emulationJunyan He2018-08-101-0/+30
Guest writes to vNVDIMM labels are intercepted and performed on the backend by QEMU. When the backend is a real persistent memort, QEMU needs to take proper operations to ensure its write persistence on the persistent memory. Otherwise, a host power failure may result in the loss of guest label configurations.
