When local storage setting is enabled at the zone then local primary stores attached to the host automatically gets discovered while adding the host. For already added host the discovery happens after MS is restarted. About the missing config, is it a new installation or an upgraded one? The config needs to be present in both scenarios. -Koushik > > From: [email protected] > > To: [email protected] > > Subject: RE: Possible to place guest VM swap on local storage? > > Date: Mon, 12 Aug 2013 20:24:27 -0400 > > > > Your suggestion is exactly the process I attempted to follow, but it was not > permitted,which is why I have come to the forum.
