Description Joe Talerico 2015-11-17 00:04:00 UTC

Description of problem:
With zero swap being deployed with our overcloud (https://bugzilla.redhat.com/show_bug.cgi?id=1259539) we should really bump the reserved_host_memory to allocate a realistic amount of memory used. 

Right now we default to 512MB. My idle compute node was consuming 1230MB. I would recommend setting this value to 2048MB on the compute nodes.

This bug did not make the OSP 8.0 release.  It is being deferred to OSP 10.

Comment 8 Red Hat Bugzilla Rules Engine 2017-02-07 00:10:26 UTC

This bugzilla has been removed from the release and needs to be reviewed and Triaged for another Target Release.

This was fixed incidentally here:
