Hi Dave,
Hi, I'm getting COLO running on a couple of our machines here and wanted to see what was actually going on, so I merged in my recent rolling-stats code: http://lists.gnu.org/archive/html/qemu-devel/2015-03/msg00648.html with the following patch, and now I get on the primary side, info migrate shows me: capabilities: xbzrle: off rdma-pin-all: off auto-converge: off zero-blocks: off colo: on Migration status: colo total time: 0 milliseconds colo checkpoint (ms): Min/Max: 0, 10000 Mean: -1.1415868e-13 (Weighted: 4.3136025e-158) Count: 4020 Values: 0@1425561742237, 0@1425561742300, 0@1425561742363, 0@1425561742426, 0@1425561742489, 0@1425561742555, 0@1425561742618, 0@1425561742681, 0@1425561742743, 0@1425561742824 colo paused time (ms): Min/Max: 55, 2789 Mean: 63.9 (Weighted: 76.243584) Count: 4019 Values: 62@1425561742237, 62@1425561742300, 62@1425561742363, 62@1425561742426, 61@1425561742489, 65@1425561742555, 62@1425561742618, 62@1425561742681, 61@1425561742743, 80@1425561742824 colo checkpoint size: Min/Max: 18351, 2.1731606e+08 Mean: 150096.4 (Weighted: 127195.56) Count: 4020 Values: 211246@1425561742238, 186622@1425561742301, 227662@1425561742364, 219454@1425561742428, 268702@1425561742490, 96334@1425561742556, 47086@1425561742619, 42982@1425561742682, 55294@1425561742744, 145582@1425561742825 which suggests I've got a problem with the packet comparison; but that's a separate issue I'll look at.
There is an obvious mistake we have made in proxy, the macro 'IPS_UNTRACKED_BIT' in colo-patch-for-kernel.patch should be 14, so please fix it before do the follow test. Sorry for this low-grade mistake, we should do full test before issue it. ;) To be honest, the proxy part in github is not integrated, we have cut it just for easy review and understand, so there may be some mistakes. Thanks, zhanghailiang
