With Qemu 4.2 we encountered a problem with unix sockets and SSH socket
forwarding for drive-mirror. It seems the socket gets reopened again and
again after it closes for some reason. This can be worked around by
specifying 'block-job-cancel' instead of 'block-job-complete' when we're
not
As the NBD server spawned by qemu can only listen on a single socket,
we're dependent on a version being passed to vm_start that indicates
which protocol can be used, TCP or Unix, by the source node.
The change in socket type (TCP to Unix) comes with a different URI. For
unix sockets it has the
The reuse of the tunnel, which we're opening to communicate with the target
node and to forward the unix socket for the state migration, for the NBD unix
socket requires adding support for an array of sockets to forward, not just a
single one. We also have to change the $sock_addr variable to an
For secure live migration with local disks via NBD over a unix socket,
we have to somehow communicate from the source node to the target node
if it supports it. This is because there can only be one NBD server with
exactly one socket bound.
The source node passes that information via STDIN.
Currently NBD storage migration always uses unencrypted TCP. The
following 4 patches add support for unix sockets that are forwarded over
SSH.
For backwards compatibility this requires some kind of communication
from the source node to the target node, because the NBD server can only
be started

Except for a slight rewording of the message in patch 2 it's exactly the same,

Where do you run into that actually? I can get my arch container to

Casually looked over the patches, looking good to me so far - I'll give
them some testing later.

This
by re-using a dirty bitmap that represents changes since the divergence
of source and target volume. requires a qemu that supports incremental
drive-mirroring, and will die otherwise.

I recently picked up and finished some work-in-progress patches for
