I see this went by:

And I wonder if this will solve the problem of a peer-to-peer migration, using non-shared storage, failing because it appears to take a bit too lon? I see in other threads Dr. Gilbert is making changes related to post copy and I am very interested in getting resolution to what appears to be a timeout problem.

Any comments would be appreciated by this newbie to Qemu.
