[Qemu-devel] [RFC PATCH v2 00/12] mc: fault tolerante through micro-checkpointing

[mrhines]

From: "Michael R. Hines" <address@hidden>

Changes since v1:

1. Re-based against Juan's improved migration_bitmap performance changes
2. Overhauled RDMA support to prepare for better usage of RDMA in 
   other parts of the QEMU code base (such as storage).
3. Fix for netlink issues that failed to cleanup the network buffer
   device for development testing.

Michael R. Hines (12):
  mc: add documentation for micro-checkpointing
  mc: timestamp migration_bitmap and KVM logdirty usage
  mc: introduce a 'checkpointing' status check into the VCPU states
  mc: support custom page loading and copying
  rdma: accelerated memcpy() support and better external RDMA user
    interfaces
  mc: introduce state machine changes for MC
  mc: introduce additional QMP statistics for micro-checkpointing
  mc: core logic
  mc: configure and makefile support
  mc: expose tunable parameter for checkpointing frequency
  mc: introduce new capabilities to control micro-checkpointing
  mc: activate and use MC if requested
