The RDMA QIOChannel does not support bi-directional communication, so when RDMA
live migration with postcopy enabled, the source qemu return path get qemu file
error.
These patches implement bi-directional communication for RDMA QIOChannel and
disable the RDMA WRITE during the postcopy phase.
This patch just make postcopy works, and will improve performance later.
[v2]
- does not update bytes_xfer when disable RDMA WRITE (David)
- implement bi-directional communication for RDMA QIOChannel (Daniel)
Please, review.
Lidong Chen (5):
migration: disable RDMA WRITE after postcopy started
migration: create a dedicated connection for rdma return path
migration: remove unnecessary variables len in QIOChannelRDMA
migration: implement bi-directional RDMA QIOChannel
migration: Stop rdma yielding during incoming postcopy
