Subject: Increase default for NovaReservedHostMemory to 4096
X-Git-Tag: opnfv-6.0.0~618
X-Git-Url: https://gerrit.opnfv.org/gerrit/gitweb?a=commitdiff_plain;h=cbf74d6e614aad829b93f99357d87eae0db6bca5;p=apex-tripleo-heat-templates.git

Increase default for NovaReservedHostMemory to 4096

Idle compute nodes are found to already consume ~1.5GB of memory, so
2GB is a bit tight.  Increasing to 4GB to be on the safe side.  Also
see https://bugzilla.redhat.com/show_bug.cgi?id=1341178
