Updates from 2 to 3: -Set AynchronousMethodsSupported to "" - this value isn't needed for creating a snapshot Updates from 1 to 2: -Remove import of CIM_ERR_FAILED -Add test description -Add comment explaining which snapshot type is being used Signed-off-by: Kaitlin Rupert <karupert@us.ibm.com> diff -r f12adddd10e4 -r 6b732da8f7fd suites/libvirt-cim/cimtest/VirtualSystemSnapshotService/03_create_snapshot.py --- /dev/null Thu Jan 01 00:00:00 1970 +0000 +++ b/suites/libvirt-cim/cimtest/VirtualSystemSnapshotService/03_create_snapshot.py Mon May 11 15:51:33 2009 -0700 @@ -0,0 +1,147 @@ +#!/usr/bin/python +# +# Copyright 2009 IBM Corp. +# +# Authors: +# Kaitlin Rupert <karupert@us.ibm.com> +# +# This library is free software; you can redistribute it and/or +# modify it under the terms of the GNU General Public +# License as published by the Free Software Foundation; either +# version 2.1 of the License, or (at your option) any later version. +# +# This library is distributed in the hope that it will be useful, +# but WITHOUT ANY WARRANTY; without even the implied warranty of +# MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
