This series focus on COLO-proxy remote colo-frame support.
Xen COLO-frame is the first user. We add a new chardev socket
in colo-compare as the way of communicate with remote COLO-frame.
And remote COLO-frame notify colo-proxy part depend on this serise:

Can you explain a bit more about how the 'remote colo-frame' works?
Is this the comparison that's separate or what?

COLO consists of three modules, colo-frame, colo-proxy, block-replication.
If we use qemu/kvm COLO, the three parts all in qemu side.
If we use Xen COLO, the colo-frame in Xen side(the remote COLO-frame),
and colo-proxy,block-replication in qemu side. So, in this case,
remote colo-frame need use qmp command and socket connect to block-replication
and colo-proxy finish COLO job.
KVM COLO and Xen COLO use the same colo-proxy to compare net packet.

Thanks

I will send another part of this series after depend patchset have
been merged.

V3:
  - Fix codestyle.

V2:
  - Rename this series.
  - Change communication way to remote colo-frame.
  - Some bugfix.
  - Split the main function, anther part wait depend patchset.


Zhang Chen (3):
   COLO-compare: Add new parameter for communicate with remote colo-frame
   COLO-compare: Add remote checkpoint notify chardev socket handler
     frame
   COLO-compare: Add remote initialization and checkpoint notification
