From cbf74d6e614aad829b93f99357d87eae0db6bca5 Mon Sep 17 00:00:00 2001 From: Sven Anderson Date: Tue, 16 May 2017 17:44:55 +0200 Subject: [PATCH] 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.
