[libvirt] VolumeCreateXML "XML" description for ESX
Hello, I am using libvirt 0.8.6 "python bindings " can someone point me to where i find the XML description of creating volumes using storagecolumecreateXML function ? i am getting libvir: ESX error : internal error Volume name 'nameXXXX.vmdk' doesn't have expected format '<directory>/<file>' thank you regards, Sherif

Hi Sherif, In theory, it's probably supposed to work with the "standard" storage and pool XML format documented here: http://libvirt.org/formatstorage.html But, it sounds like in practise that's not working for you. Is that the case? Regards and best wishes, Justin Clift
yes i am using same template like KVM but it is not working, seems ESX driver has a different XML structure since it is using datatstore /dir/filename.vdk structure. so any idea what is the XML structure for creating the XML for volumes using the ESX driver?

Matthias, sounds like there's a bug or we need to update the docs? On 02/12/2010, at 11:02 PM, Sherif Nagy wrote:

This XML snippet should work <volume> <name>test_vm/test_vm.vmdk</name> <allocation>0</allocation> <capacity unit='G'>2</capacity> </volume> The error message says that the volume name doesn't have the expected format <directory>/<file>. The <> might be misleading here, they don't refer to XML elements. I can probably relax this and allow files in the datastore root. The problem with a .vmdk file in the datastore root is that ESX doesn't allow a virtual machine to be registered (or defined in libvirt terms) in the datastore root. The typical layout is to have a subdirectory per virtual machine. Matthias 2010/12/2 Sherif Nagy <sherif.nagy@gmail.com>:

Works for me with the given XML config. There might be some cases that could make it fail. For example the .vmdk file already exists, or the datastore is full, or the datastore is NFS backed and the ESX server lost the connection, etc. Unfortunately libvirt doesn't include detailed information into this error message. I'm currently improving this. For now you can get detailed error information from the managed object browser (mob). You can access it here: https://<your-esx-server-name>/mob Then follow this chain of links: content > taskManager > recentTask and pick the last item in the list. It should be named like this: haTask--vim.VirtualDiskManager.createVirtualDisk-88 This is probably the failed .vmdk creation task. Then follow this second chain of links: info > error to get more detailed error information. As said the next libvirt release will include this more detailed information in error messages for failed tasks. Matthias 2010/12/2 Sherif Nagy <sherif.nagy@gmail.com>:

thank you Matthias, i did follow what you said and i find the error, I am connecting to vCenter server not to ESX directly and that what i have find.
Data Object Type: *NotImplemented*
That's the important information. The vCenter doesn't seem to implement the method to create a new volume. I wonder how a vSphere Client connected to a vCenter does volume creation. I'll have to investigate this. Matthias
