[17:39] * ducttape_ has quit (Remote host closed the connection)
[17:39] <inc0> and we *have to* configure cells now?
[17:41] <diana_clarke> inc0: yes, cells v2 setup is required as of ocata
[17:42] <inc0> http://docs.openstack.org/developer/nova/cells.html#cells-v2 this is correct doc right?
[17:42] <diana_clarke> inc0: I'm just pulling up some links for you (sorry if that sounded short/terse a moment ago).
[17:43] <diana_clarke> inc0: yup, that a good one to read

[17:43] <inc0> diana_clarke, it did not:) it sounded nothing but helpful:)
