From: "Dr. David Alan Gilbert" <dgilbert@redhat.com>
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.
