Kashyap Chamarthy ca03fe8737 libvirt: Don't disregard cache mode for instance boot disks ... One of the things this commit: commit 14c38ac0f2 Author: Kashyap Chamarthy <kchamart@redhat.com> Date: Thu Jul 20 19:01:23 2017 +0200 libvirt: Post-migration, set cache value for Cinder volume(s) [...] did was to supposedly remove "duplicate" calls to _set_cache_mode(). But that came back to bite us. Now, while the Cinder volumes are taken care of w.r.t handling its cache value during migration, but the above referred commit (14c38ac) seemed to introduce a regression because it disregards the 'disk_cachemodes' Nova config parameter altogether for boot disks -- i.e. even though if a user set the cache mode to be 'writeback', it's ignored and instead 'none' is set unconditionally. Add the _set_cache_mode() calls back in _get_guest_storage_config().
