Github user kiwiflyer commented on the issue: https://github.com/apache/cloudstack/pull/977 @ustcweizhou @rhtyd So the vmsnapshot test seems might need some work. Here's the exception it threw: 2017-01-10 17:27:01,025 - CRITICAL - EXCEPTION: test_01_create_vm_snapshots: ['Traceback (most recent call last):\n', ' File "/usr/lib64/python2.7/unittest/case.py", line 369, in run\n testMethod()\n', ' File "/marvin/tests/smoke/test_vm_snapshots.py", line 158, in test_01_create_vm_snapshots\n "Dsiplay Text"\n', ' File "/usr/lib/python2.7/site-packages/marvin/lib/base.py", line 4702, in create\n return VmSnapshot(apiclient.createVMSnapshot(cmd).__dict__)\n', ' File "/usr/lib/python2.7/site-packages/marvin/cloudstackAPI/cloudstackAPIClient.py", line 1281, in createVMSnapshot\n response = self.connection.marvinRequest(command, response_type=response, method=method)\n', ' File "/usr/lib/python2.7/site-packages/marvin/cloudstackConnection.py", line 379, in marvinRequest\n raise e\n', 'CloudstackAPIException: Execute cmd: createvmsnapshot failed, due to: errorCode: 431, errorText:KVM VM does not allow to take a disk-only snapshot when VM is in running state\n'] The nuance here is that you need to specify snapshotmemory=true in order to take a KVM snapshot with the VM running.
