[Qemu-devel] [PATCH v4 00/29] postcopy+vhost-user/shared ram

[Dr. David Alan Gilbert (git)]

From: "Dr. David Alan Gilbert" <address@hidden>

  This set enables postcopy migration with shared memory to a vhost user 
process.
It's based off current head.

  Testing is mostly performed with dpdk, with corresponding modifications by
Maxime.

  v4 is mostly just fixes from comments received during review of v3,
and the normal updating of all the virtio enum's to catch up with other
things getting in before us.
