[Libvirt-cim] Xen Domain Management CIM-Provider

I am trying to understand the provider implementation for Xen VM lifecycle management. Does the xen provider (libvirt/xen-cim) uses the xenstore to access/change the configuration information regarding the domains. e.g if Xen Client has to changes the memory allocation for any of the domain (i assume discover of domain/UUID/domid is already done) then can it uses xenstore to perform the operation in following way. *xenstore-write /local/domain/domid/memory/target <value> (balloon watch node)* Or Is there any other method to perform the same operations. thanks in advance for any information or pointers Tej
