[Qemu-devel] [PATCH v2 0/5] Enable postcopy RDMA live migration

Posted by Lidong Chen 7 years, 6 months ago

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
