2018-05-01 09:36:05 quanxian description Description: When the host persistent memory is used as the backend of vNVDIMM, QEMU itself may write to the host pmem, e.g., in vNVDIMM label emulation and live migration. In those cases, QEMU needs to take necessary operations (e.g., flush&fence after writes, or store with non-temporal hint) to ensure the data persistence of its own writes to PMEM. Therefore, data on vNVDIMM can be in a consistent status on abnormal termination of QEMU (e.g., QEMU/host kernel crash, host power failure, etc.). Unfortunately, such operations are missed in current QEMU implementation. Target Qemu Release:2.13 Target Release: 18.04 Description: When the host persistent memory is used as the backend of vNVDIMM, QEMU itself may write to the host pmem, e.g., in vNVDIMM label emulation and live migration.
