Do you mean that the ESX driver doesn't use CloneVM_Task() or that the ESX server returns an NotImplemented fault for a call to CloneVM_Task()? > Does anyone know the best way to still implement this function or a > workaround ? > Why is it not already implemented ? It's not implemented in libvirt, because libvirt doesn't have a virDomainClone() function, so there is no way for the ESX driver to use CloneVM_Task(). The virt-clone tool uses several libvirt functions to perform a clone operation. The basics steps are: - get the domain XML description of the domain to clone - determine the storage volumes to clone - issue a virStorageVolCreateXMLFrom() for each storage volume to be cloned - update the storage volume references in the domain XML description; remove the uuid and mac addresses to get new ones - define a new domain from the edited domain XML description You should be able to implement a clone operation for ESX on top of libvirt without the need to change libvirt. Or try to use virt-clone for ESX. IIRC virt-clone currently doesn't handle the VMware path format properly so it might need some tweaks.
