8 See the COPYING file in the top-level directory.
13 COLO-proxy is a part of COLO project. It is used
15 whether to do checkpoint. With COLO-proxy's help,
18 The filter-redirector, filter-mirror, colo-compare
19 and filter-rewriter compose the COLO-proxy.
23 COLO-Proxy is based on qemu netfilter and it's a plugin for qemu netfilter
24 (except colo-compare). It keep Secondary VM connect normally to
26 If the packet difference, notify COLO-frame to do checkpoint and send

73 Tap --> Mirror Client Filter
80 Mirror Server Filter --> TCP Rewriter
89 Guest --> Redirect Server Filter
93 Redirect Server Filter --> COLO-Compare
94 COLO-compare receive primary guest packet then
100 COLO-Compare --> Another Redirector Filter
101 The redirector get packet from colo-compare by use
104 Redirector Filter --> Tap
109 Guest --> TCP Rewriter Filter
115 Redirect Client Filter --> Redirect Server Filter
120 Filter-mirror is a netfilter plugin.
124 Filter-redirector is a netfilter plugin.

145 COLO-compare, we do packet comparing job.
148 COLO-compare needs two input chardevs and one output chardev:
149 primary_in=chardev1-id (source: primary send packet)
150 secondary_in=chardev2-id (source: secondary send packet)
151 outdev=chardev3-id
153 Filter-rewriter will rewrite some of secondary packet to make

214 a.COLO-proxy must work with COLO-frame and Block-replication.
215 b.Primary COLO must be started firstly, because COLO-proxy needs
217 c.Filter-rewriter only rewrite tcp packet.
