From e957b50b8daecfc39a1ac09855b0eacb6edfd328 Mon Sep 17 00:00:00 2001 From: Leonid Bloch Date: Wed, 26 Sep 2018 19:04:46 +0300 Subject: qcow2: Set the default cache-clean-interval to 10 minutes The default cache-clean-interval is set to 10 minutes, in order to lower the overhead of the qcow2 caches (before the default was 0, i.e. disabled). * For non-Linux platforms the default is kept at 0, because cache-clean-interval is not supported there yet.
