Re: [Libvirt-cim] [PATCH] (#4) Add read-only support

# HG changeset patch # User Eduardo Lima (Etrunko)&lt;eblima(a)br.ibm.com&gt; # Date 1308270993 14400 # Node ID 83f0e989145d86bc84dac05ef371c536a9734673 # Parent a2f523cd39c29977ed07247a38316d44f5123874 Add read-only support. This patch enables a consumer of libvirt-cim to put it in read-only mode by adding the key-value pair 'readonly=true' to libvirt-cim.conf. Also clean-up some extra whitespace in touched files.
