Hi all, In our production environment, we enables glance_store for VMware datastore. Configuration in glance-api.conf: [DEFAULT] show_image_direct_url = True [glance_store] stores= glance.store.vmware_datastore.Store default_store = vsphere vmware_server_host= 172.18.6.22 vmware_server_username = administrator at vsphere.local vmware_server_password = 1qaz!QAZ vmware_datastores = ICT Test:F7-HPP9500-SAS-ICTHPCLUSTER03-LUN06 Firstly we boot an instance, make online snapshot for the VM, we see the image stores on local file system: direct_url file:///var/lib/glance/images/8cf7ba51-31d8-4282-89db-06957d609691 Then we poweroff the VM, make offline snapshot, the image stores on VMware datastore: direct_url vsphere:// 172.20.2.38/folder/openstack_glance/52825a70-f645-46b5-80ec-7a430dcd13cf?dcPath=IDC_Test&dsName=LUN03-00 In Nova VCDriver, make snapshot will upload VM disk file to Glance image server. But why different behaviour for the VM poweron and poweroff? Hopes for your reply. -------------- next part -------------- An HTML attachment was scrubbed...
