Re: [libvirt] virsh: Can't create .vmdk virtual disk over vCenter while over ESX it works well

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.
