Hello,

I am trying to create the virtual disk over "virsh". My target is the ESX server that is a part of the vCenter. That is why I connect to it using the vpx://-like URL. The connection itself is being established correctly. Commands like "list --all", "dumpxml <machine>" "vol-dumpxml <volume>" work perfectly well. What doesn't work for me at the moment is "vol-create --file <xml_file> --pool <my_pool>". I would suspect that I am passing some parameters incorrectly and would be digging more into a documentation but I am getting the following response from the server:

virsh # vol-create --file vadp4.xml --pool "iscsi-esx4-1" error: Failed to create vol from vadp4.xml error: internal error Could not create volume: NotImplemented - Der angeforderte  Vorgang wird vom Server nicht implementiert.

I have to admit that the very same command worked if I connect to ESX server directly (using esx://-like URL).

My question is if it is planned to implement the virtual disk creation in case of vCentere is involved ?

The error message is a bit misleading, but expected. The NotImplemented error actually comes from the vCenter Server, that doesn't seem to support forwarding CreateVirtualDisk_Task calls to the ESX servers. I haven't figured out yet how the vSphere Client connected to a vCenter Server manages to do disk creation. So you could consider this a missing workaround in libvirt, or the lack of proper knowledge about how to do disk creation via a vCenter Server. Matthias
