[Qemu-devel] [RFC 0/1] Rolling stats on colo

[Dr. David Alan Gilbert (git)]

From: "Dr. David Alan Gilbert" <address@hidden>

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: address@hidden, address@hidden, 
address@hidden, address@hidden, address@hidden, address@hidden, address@hidden, 
address@hidden, address@hidden, address@hidden
colo paused time (ms): Min/Max: 55, 2789 Mean: 63.9 (Weighted: 76.243584) 
Count: 4019 Values: address@hidden, address@hidden, address@hidden, 
address@hidden, address@hidden, address@hidden, address@hidden, address@hidden, 
address@hidden, address@hidden
colo checkpoint size: Min/Max: 18351, 2.1731606e+08 Mean: 150096.4 (Weighted: 
127195.56) Count: 4020 Values: address@hidden, address@hidden, address@hidden, 
address@hidden, address@hidden, address@hidden, address@hidden, address@hidden, 
address@hidden, address@hidden

which suggests I've got a problem with the packet comparison; but that's
a separate issue I'll look at.

Dave
